Source Description
UniProtProbable transcriptional activator that promotes early floral meristem identity (PubMed:7919989). Is required subsequently for the transition of an inflorescence meristem into a floral meristem (PubMed:1675158). Plays a central role in the specification of floral identity, particularly for the normal development of sepals and petals in the wild-type flower, by spatially controlling the expression domains of multiple floral organ identity genes (PubMed:1675158, PubMed:23034631). Acts as A class cadastral protein by repressing the C class floral homeotic gene AGAMOUS in association with other repressors like LEUNIG and SEUSS (PubMed:1675158). Directly represses AGAMOUS by recruiting the transcriptional corepressor TOPLESS and the histone deacetylase HDA19 (PubMed:23034631). It is also required during seed development (PubMed:1675158). {ECO:0000269|PubMed:1675158, ECO:0000269|PubMed:23034631, ECO:0000269|PubMed:7919989}.
Regulation -- Description ? help Back to Top
Source Description
UniProtINDUCTION: Negatively regulated by the C class floral homeotic protein AGAMOUS in stamens and carpels. MicroRNA 172 (miRNA172) negatively regulates APETALA2 at the translational level and may modulate its expression pattern. Seems not to be influenced by jasmonate and Alternaria brassicicola. {ECO:0000269|PubMed:12805630, ECO:0000269|PubMed:12893888, ECO:0000269|PubMed:14555699}.
