SAC51 is a bHLH(basic helix-loop-helix)-type transcription factor. It is involved in stem elongation, probably by regulating a subset of genes involved in this process.
NAC074, ANAC074, KIR1, KIRA1, NAC DOMAIN CONTAINING PROTEIN 74
Background:
NAC074 is a member of NAC family of transcription factors. That protein along with NAC2, KIR1 positively regulates programmed cell death of stigmatic tissue.
