unc-37 encodes a transducin-like WD-repeat protein orthologous to Drosophila Groucho; unc-37 plays an essential role in embryonic and neuronal fate specification; unc-37 genetically interacts with components of the transcriptional Mediator complex.
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and transcription corepressor activity. Involved in chemical synaptic transmission; regulation of axonogenesis; and regulation of synapse structure or activity. Located in nucleus. Expressed in several structures, including germ line; head; and tail. Is an ortholog of human TLE2 (TLE family member 2, transcriptional corepressor).
