Protein: Nuclear transcription factor Y subunit B-2 (OsNF-YB-2) (Transcriptional activator HAP3A) (Q5QMG3)
Organism: Oryza sativa subsp. japonica (Rice)
Function: Component of the NF-Y/HAP transcription factor complex. The NF-Y complex stimulates the transcription of various genes by recognizing and binding to a CCAAT motif in promoters. May regulate the expression of photosynthetic genes, and may be involved in chloroplast and amyloplast development.
Subcellular location: Nucleus {ECO:0000305}.
