NCBI Protein Information
POX (plant homeobox) family protein
NCBI Summary
Homeodomain protein required for ovule identity.Loss of function mutations show homeotic conversion of integuments to carpels.Forms heterodimers with STM and KNAT1. Interacts with AG-SEP heterodimers is thought to restrict WUS expression. BEL interacts with MADS box dimers composed of SEP1(or SEP3) and AG, SHP1, SHP2 and STK. The interaction of BEL1 with AG-SEP3 is required for proper integument development and specification of integument identity.

UniProt Comments
Plays a major role in ovule patterning and in determination of integument identity via its interaction with MADS-box factors. Formation of complex with AG-SEP dimers negatively regulates the carpel identity process and favors the maintenance of ovule identity. BEL1-STM complex maintains the indeterminacy of the inflorescence meristem. Required, with SPL, for cytokinin-induced PIN1 expression in ovules (PubMed:22786869).
