Enables transcription cis-regulatory region binding activity. Contributes to sequence-specific DNA binding activity. Involved in R7 cell differentiation and positive regulation of DNA-templated transcription. Part of CCAAT-binding activity factor complex. Is expressed in embryonic brain; larval ventral nerve cord; and organism. Orthologous to human NFYA (nuclear transcription factor Y subunit alpha).
FB Description
Nuclear factor Y-box A (Nf-YA) encodes a subunit of the nuclear transcription factor Y (NF-Y), also known as the CCAAT motif-binding factor (CBF). It is involved in eye and thorax development via gene expression regulation.
