Predicted to enable DNA binding activity and DNA-binding transcription activator activity, RNA polymerase II-specific. Predicted to contribute to RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of transcription, DNA-templated. Part of CCAAT-binding activity factor complex. Orthologous to human NFYC (nuclear transcription factor Y subunit gamma). [provided by Alliance of Genome Resources, Apr 2022]
