Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and protein heterodimerization activity. Predicted to be involved in regulation of DNA-templated transcription. Predicted to be part of CCAAT-binding activity factor complex. Is an ortholog of C. elegans
nfyb-1. In C. elegans,
nfyb-1 is involved in negative regulation of transcription by RNA polymerase II and tissue development.
