MTA2 was initially recognized as an MTA1 like 1 gene, named MTA1-L1, from a large scale sequencing of randomly selected clones from human [[cDNA]] libraries in 1999.<ref name="1-Futamura" /> Clues about the role of MTA2 in gene expression came from the association of MTA2 polypeptides in the NuRD complex in a proteomic study<ref name="2-zhang" /> This was followed by targeted cloning of murine Mta2 in 2001.<ref name="7-xia">{{cite journal | vauthors = Xia L, Zhang Y | title = Sp1 and ETS family transcription factors regulate the mouse Mta2 gene expression | journal = Gene | volume = 268 | issue = 1-2 | pages = 77–85 | date = May 2001 | pmid = 11368903 | doi=10.1016/s0378-1119(01)00429-2}}</ref>
 
== Gene and spliced variants ==
 
MTA2 is localized on chromosome 11q12-q13.1 in human and on 19B in mice. The 8.6-kb long human MTA2 gene contains 20 exons and seven transcripts inclusive of three protein-coding transcripts but predicted to code for two polypeptides of 688 amino acids and 495 amino acids.<ref name="8-Kumar">{{cite journal | vauthors = Kumar R, Wang RA | title = Structure, expression and functions of MTA genes | journal = Gene | volume = 582 | issue = 2 | pages = 112–21 | date = May 2016 | pmid = 26869315 | doi = 10.1016/j.gene.2016.02.012 }}</ref> The remaining four MTA2 transcripts are non-coding RNA transcripts ranging from 532-bp to 627-bp.

Amino acid sequence of MTA2 shares 68.2% homology with [[MTA1]]’s sequence. MTA2 domains include, a [[BAH domain|BAH]] (Bromo-Adjacent Homology), a [[ELM2]] (egl-27 and MTA1 homology), a [[SANT domain]] (SWI, ADA2, N-CoR, TFIIIB-B), and a GATA-like [[zinc finger]].<ref name="9-mil">{{cite journal | vauthors = Millard CJ, Watson PJ, Celardo I, Gordiyenko Y, Cowley SM, Robinson CV, Fairall L, Schwabe JW | title = Class I HDACs share a common mechanism of regulation by inositol phosphates | journal = Molecular Cell | volume = 51 | issue = 1 | pages = 57–67 | date = Jul 2013 | pmid = 23791785 | doi = 10.1016/j.molcel.2013.05.020 | pmc=3710971}}</ref><ref name="10-al">{{cite journal | vauthors = Alqarni SS, Murthy A, Zhang W, Przewloka MR, Silva AP, Watson AA, Lejon S, Pei XY, Smits AH, Kloet SL, Wang H, Shepherd NE, Stokes PH, Blobel GA, Vermeulen M, Glover DM, Mackay JP, Laue ED | title = Insight into the architecture of the NuRD complex: structure of the RbAp48-MTA1 subcomplex | journal = The Journal of Biological Chemistry | volume = 289 | issue = 32 | pages = 21844–55 | date = Aug 2014 | pmid = 24920672 | doi = 10.1074/jbc.M114.558940 | pmc=4139204}}</ref><ref name="11-mil">{{cite journal | vauthors = Millard CJ, Fairall L, Schwabe JW | title = Towards an understanding of the structure and function of MTA1 | journal = Cancer Metastasis Reviews | volume = 33 | issue = 4 | pages = 857–67 | date = Dec 2014 | pmid = 25352341 | doi = 10.1007/s10555-014-9513-5 | pmc=4244562}}</ref> MTA2 is acetylated at lysine 152 within the BAH domain<ref name="12-zhou">{{cite journal | vauthors = Zhou J, Zhan S, Tan W, Cheng R, Gong H, Zhu Q | title = P300 binds to and acetylates MTA2 to promote colorectal cancer cells growth | journal = Biochemical and Biophysical Research Communications | volume = 444 | issue = 3 | pages = 387–90 | date = Feb 2014 | pmid = 24468085 | doi = 10.1016/j.bbrc.2014.01.062 }}</ref>
 
== Function ==
 
This gene encodes a protein that has been identified as a component of [[NuRD]], a nucleosome remodeling deacetylase complex identified in the nucleus of human cells. It shows a very broad expression pattern and is strongly expressed in many tissues. It may represent one member of a small gene family that encode different but related proteins involved either directly or indirectly in transcriptional regulation. Their indirect effects on transcriptional regulation may include [[chromatin remodeling]].<ref name="entrez" />
 
MTA2 inhibits [[estrogen receptor]]-transactivation functions, and participates in the development of hormones independent of breast cancer cells.<ref name="6-covin" /> The MTA2 participate in the circadian rhythm through CLOCK-BMAL1 complex. MTA2 inhibits the expression of target genes owing to its ability to interact with chromatin remodeling complexes, and modulates pathways involved in cellular functions, including invasion, apoptosis, epithelial-to-mesenchymal transition, and growth of normal and cancer cells<ref name="4-sen" /><ref name="6-covin" />

Their indirect effects on transcriptional regulation may include chromatin remodeling. It is closely related to another member of this family, a protein that has been correlated with the metastatic potential of certain carcinomas. These two proteins are so closely related that they share the same types of domains. These domains include two DNA binding domains, a dimerization domain, and a domain commonly found in proteins that methylate DNA. One of the proteins known to be a target protein for this gene product is p53. Deacteylation of p53 is correlated with a loss of growth inhibition in transformed cells supporting a connection between these gene family members and metastasis.<ref name="entrez">{{cite web | title = Entrez Gene: MTA2 metastasis associated 1 family, member 2| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=9219| accessdate = }}</ref>

Metastasis-associated protein MTA2 is a protein that in humans is encoded by the MTA2 gene.[1][2]

MTA2 is the second member of the MTA family of genes.[1][3][4] MTA2 protein localizes in the nucleus and is a component of the nucleosome remodeling and the deacetylation complex (NuRD).[4] Similar to the founding family member MTA1, MTA2 functions as a chromatin remodeling factor and regulates gene expression.[5][6] MTA2 is overexpressed in human cancer and its dysregulated level correlates well with cancer invasiveness and aggressive phenotypes.[7]

Discovery

MTA2 was initially recognized as an MTA1 like 1 gene, named MTA1-L1, from a large scale sequencing of randomly selected clones from human cDNA libraries in 1999.[1] Clues about the role of MTA2 in gene expression came from the association of MTA2 polypeptides in the NuRD complex in a proteomic study[3] This was followed by targeted cloning of murine Mta2 in 2001.[8]

Gene and spliced variants

MTA2 is localized on chromosome 11q12-q13.1 in human and on 19B in mice. The 8.6-kb long human MTA2 gene contains 20 exons and seven transcripts inclusive of three protein-coding transcripts but predicted to code for two polypeptides of 688 amino acids and 495 amino acids.[9] The remaining four MTA2 transcripts are non-coding RNA transcripts ranging from 532-bp to 627-bp. The murine Mta2 consists of a 3.1-kb protein-coding transcript to code a protein of 668 amino acids, and five non-coding RNAs transcripts, ranging from 620-bp to 839-bp.

Structure

Amino acid sequence of MTA2 shares 68.2% homology with MTA1’s sequence. MTA2 domains include, a BAH (Bromo-Adjacent Homology), a ELM2 (egl-27 and MTA1 homology), a SANT domain (SWI, ADA2, N-CoR, TFIIIB-B), and a GATA-like zinc finger.[10][11][12] MTA2 is acetylated at lysine 152 within the BAH domain[13]

Function

This gene encodes a protein that has been identified as a component of NuRD, a nucleosome remodeling deacetylase complex identified in the nucleus of human cells. It shows a very broad expression pattern and is strongly expressed in many tissues. It may represent one member of a small gene family that encode different but related proteins involved either directly or indirectly in transcriptional regulation. Their indirect effects on transcriptional regulation may include chromatin remodeling.[2]

MTA2 inhibits estrogen receptor-transactivation functions, and participates in the development of hormones independent of breast cancer cells.[7] The MTA2 participate in the circadian rhythm through CLOCK-BMAL1 complex. MTA2 inhibits the expression of target genes owing to its ability to interact with chromatin remodeling complexes, and modulates pathways involved in cellular functions, including invasion, apoptosis, epithelial-to-mesenchymal transition, and growth of normal and cancer cells[5][7]

Regulation

Expression of MTA2 is stimulated by Sp1 transcription factor [8][14] and repressed by Kaiso.[15] Growth regulatory activity of MTA2 is modulated through its acetylation by histone acetylase p300 [12]. The expression of MTA2 is inhibited by the Rho GDIa in breast cancer cells[16] and by human β-defensins in colon cancer cells.[17] MicroRNAs-146a and miR-34a also regulate the levels of MTA2 mRNA through post-transcriptional mechanism.[18][19][20]

Targets

MTA2 deacetylates the estrogen receptor alpha and p53 and inhibits their transactivation functions.[21][22] MTA2 represses the expression of E-cadherin in non-small-cell lung cancer cells.[23] but stimulates the expression of IL-11 in gastric cancer cells.[24] The MTA2-containing chromatin remodeling complex targets CLOCK-BMAL1 complex.[25]

Interactions

MTA2 has been shown to interact with:
