Functional Description ? help Back to Top
Source	Description
UniProt	Probable transcription factor involved in the control of organ identity during the early development of flowers. Is required for normal development of stamens and carpels in the wild-type flower. Plays a role in maintaining the determinacy of the floral meristem. Acts as C class cadastral protein by repressing the A class floral homeotic genes like APETALA1. Forms a heterodimer via the K-box domain with either SEPALATTA1/AGL2, SEPALATTA2/AGL4, SEPALLATA3/AGL9 or AGL6 that could be involved in genes regulation during floral meristem development. Controls AHL21/GIK, a multifunctional chromatin modifier in reproductive organ patterning and differentiation (PubMed:19956801). Induces microsporogenesis through the activation of SPL/NZZ (PubMed:15254538). {ECO:0000269\|PubMed:15254538, ECO:0000269\|PubMed:19956801}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Negatively regulated by the A class floral homeotic protein APETALA2 and by other repressors like LEUNIG, SEUSS, SAP or CURLY LEAF. Positively regulated by both LEAFY and APETALA1. Repressed by silencing mediated by polycomb group (PcG) protein complex containing EMF1 and EMF2. Up-regulated by HUA2. {ECO:0000269\|PubMed:10198637, ECO:0000269\|PubMed:11058164, ECO:0000269\|PubMed:1675158, ECO:0000269\|PubMed:17794879, ECO:0000269\|PubMed:18281509, ECO:0000269\|PubMed:19783648, ECO:0000269\|PubMed:9783581}.
