Grainy head gene transcriptions

"The defined GRHL1 DNA‐binding consensus sequence (AACCGGTT) was identical to that defined for GRHL3, and also matched the consensus sequence for Drosophila GRH DNA binding, which we had previously identified by alignment of multiple GRH‐responsive gene regulatory regions (Wilanowski et al, 2002; Ting et al, 2005). Of note, the first of the two cytosines and the second of the guanines were invariant in both GRHL1 and GRHL3 CASTing assays."

"The putative GRHL1‐binding motif (GACTGGTT) is perfectly conserved, together with 6 bp upstream and 12 bp downstream flanking sequences, in three of the Dsg1 promoters: mouse Dsg1α, mouse Dsg1γ, and human DSG1 [...]. In the mouse Dsg1β promoter, this motif is slightly different (AACTGGTT), although the flanking sequences are still conserved."

"The consensus DNA‐binding sequence identified for GRHL1 is identical to that defined for Drosophila GRH (Wilanowski et al, 2002). In addition, the identification of cadherin genes as direct transcriptional targets of GRHL1 extends the links between the grh and cadherin gene families from Drosophila to mammals. The cadherin family consists of more than 100 members (including the protocadherins) involved in many diverse cellular and developmental events (Nollet et al, 2000). Among the known targets of Drosophila, GRH are two cadherin superfamily members, stan/fmi and E‐cadherin/shotgun (Lee and Adler, 2004; Almeida and Bray, 2005). The links between the two gene families have recently been extended in another model organism. A study of genome‐wide predictions of genetic interactions in C. elegans has identified a number of cadherin family members as prime targets for significant functional interactions with Grh‐1, the worm homologue of grh (Zhong and Sternberg, 2006). These included cdh‐6, a homologue of Drosophila stan, and hmp‐2, a β‐catenin. We have recently identified the mammalian homologue of E‐cadherin as a target of another member of the Grh‐like family, Grhl2 (JMC and SMJ, unpublished)."

Cadherin genes

Gene ID: 999 is CDH1 cadherin 1: "This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function of this gene is thought to contribute to cancer progression by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. This gene is present in a gene cluster with other members of the cadherin family on chromosome 16."
