Summary: This gene encodes one of testis-specific transcription factors which are essential for spermatogenesis, oogenesis and folliculogenesis. This gene is located on chromosome 13. The proteins encoded by this gene and another testis-specific transcription factor, SOHLH1, can form heterodimers, in addition to homodimers. There is a read-through locus (GeneID: 100526761) that shares sequence identity with this gene and the upstream CCDC169 (GeneID: 728591). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2013]

Data found that sohlh2 overexpression inhibited breast cancer cell proliferation in vitro and tumor growth in vivo. In contrast, sohlh2 silencing induced the opposite effects. These functional effects of sohlh2 were exerted through inhibiting Wnt/beta- catenin signaling by the increase of APC expression. These findings provide a novel mechanistic role of sohlh2 in breast tumorigenesis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
