"Maternal mRNAs are translationally regulated during early development. Zar1 and its closely related homolog, Zar2, are both crucial in early development. Xenopus laevis Zygote arrest 2 (Zar2) binds to the Translational Control Sequence (TCS) in maternal mRNAs and regulates translation."[1]

Human genes

Gene expressions

"The 3′ UTR of Wee1 mRNA contains two cytoplasmic polyadenylation elements (CPEs) and two Translational Control Sequences (TCSs) that regulate translation [17, 20]. The TCSs repress translation in immature oocytes and during maturation they confer cytoplasmic polyadenylation to the mRNA and stimulate translation. The function of the TCS is mediated by its trans-acting factor Zar2. Like the TCS, Zar2 represses translation in immature oocytes and this repression is relieved in maturing oocytes [9]. Mos is another developmentally important protein that is encoded by a maternal mRNA. The Mos protein is absent in immature oocytes and starts to be synthesized shortly after re-entry into the meiotic cell cycle. Appropriate translational control of the Mos mRNA is crucial for timely oocyte maturation and prevention of premature mitotic cell cycles [21–23]. The Mos 3′ UTR contains a CPE, a Musashi binding element (MBE), and also a TCS [9, 12, 24–26]."[1]

Interactions

Consensus sequences

Wee1 UTR probe found TCS1 AUUAUCU and TCS2 AUUGUCU.[1]

Mos probe found TCS UUUGUCU.[1] These suggest a consensus sequence of (A/U)UU(A/G)UCU, apparently excluding UUUAUCU.[1] "Putative TCSs have been identified in Wee1, PCM-1 and Mos 3′ UTRs. The TCSs are slightly different: AUUAUCU (Wee1 TCS1), AUUGUCU (Wee1 TCS2) and UUUGUCU (Mos and PCM-1 TCS) [20]".[1]

Enhancer activity

Promoter occurrences

Hypotheses

  1. A1BG has no regulatory elements in either promoter.
  2. A1BG is not transcribed by a regulatory element.
  3. No regulatory element participates in the transcription of A1BG.

TCS samplings

Copying a responsive elements consensus sequence (A/T)TT(A/G)TCT and putting the sequence in "⌘F" finds none between ZNF497 and A1BG or four between ZSCAN22 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence (A/T)TT(A/G)TCT (starting with SuccessablesAAA.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
