Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein dimerization activity. Predicted to be involved in cell differentiation; positive regulation of transcription by RNA polymerase II; and spermatogenesis. Predicted to act upstream of or within oocyte differentiation; primary ovarian follicle growth; and regulation of gene expression. Predicted to be active in nucleus. Orthologous to several human genes including CCDC169-SOHLH2 (CCDC169-SOHLH2 readthrough). [provided by Alliance of Genome Resources, Apr 2022]
