Anti-SOX30

This gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein acts as a transcriptional regulator when present in a complex with other proteins. It can activate p53 transcription to promote tumor cell apoptosis in lung cancer. The protein may be involved in the differentiation of developing male germ cells. Alternative splicing of this gene results in multiple transcript variants. A related pseudogene has been identified on chromosome 5. Protein function: Acts as both a transcriptional activator and repressor (PubMed:29866902, PubMed:29848638). Binds to the DNA sequence 5'-ACAAT- 3' and shows a preference for guanine residues surrounding this core motif (PubMed:29866902). Binds to its own promoter and activates its own transcription (PubMed:29866902, PubMed:29848638). Required to activate the expression of postmeiotic genes involved in spermiogenesis (PubMed:29866902, PubMed:29848638). Binds to the promoter region of CTNNB1 and represses its transcription which leads to inhibition of Wnt signaling (PubMed:29739711). Also inhibits Wnt signaling by binding to the CTNNB1 protein, preventing interaction of CTNNB1 with TCF7L2/TCF4. [The UniProt Consortium]
