NCBI Protein Information
RING/FYVE/PHD zinc finger superfamily protein
NCBI Summary
Sporophytic factor controlling anther and pollen development. Mutants fail to make functional pollen;pollen degeneration occurs after microspore release and the tapetum also appears abnormally vacuolated. Similar to PHD-finger motif transcription factors.

UniProt Comments
Transcriptional activator required for anther and post-meiotic pollen development and maturation. Seems to regulate inflorescence branching and floral development. May control tapetal development by directly regulating tapetal programmed cell death (PCD) and breakdown. Implicated in pollen cytosolic components and wall development (e.g. exine and intine formation).
