NCBI Protein Information
Plant-specific transcription factor YABBY family protein
NCBI Summary
YABBY gene family member, likely has transcription factor activity, involved in specifying abaxial cell fate. Along with FIL, involved in patterning of the fruit. GUS reporter gene expression in seedlings is observed in the young leaves and as the leaf matures, expression is restricted to the abaxial tissues of leaves, expression is also observed on either side of the leaf margin in the younger tissues of leaf blades.

UniProt Comments
Involved in the abaxial cell fate determination during embryogenesis and organogenesis. Regulates the initiation of embryonic shoot apical meristem (SAM) development (PubMed:10457020, PubMed:12417699, PubMed:19837869). Contributes to the repression of KNOX genes (STM, KNAT1/BP and KNAT2) to avoid ectopic meristems. Binds DNA without sequence specificity (PubMed:10457020, PubMed:12417699).
