Predicted to enable DNA-binding transcription factor activity and sequence-specific DNA binding activity. Predicted to be involved in regulation of DNA-templated transcription. Is an ortholog of C. elegans
ast-1 and
ets-8. In C. elegans,
ast-1 is involved in several processes, including nematode pharynx morphogenesis; neuron differentiation; and regulation of nematode male tail tip morphogenesis.
