NCBI Protein Information
F-box family protein
NCBI Summary
Required for the proper identity of the floral meristem. Involved in establishing the whorled pattern of floral organs, in the control of specification of the floral meristem, and in the activation of APETALA3 and PISTILLATA. UFO is found at the AP3 promoter in a LFY-dependent manner, suggesting that it works with LFY to regulate AP3 expression. UFO may also promote the ubiquitylation of LFY.

UniProt Comments
Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins . Considered as a meristem identity factor required for normal growth of the young floral meristem. Acts together with LEAFY to positively regulate the B class floral homeotic genes APETALA3 and PISTILLATA. In this way, operates as a region-specific regulator for petal and stamen development. Alternatively, may play a role as a negative regulator of the C class floral homeotic genes. Interacts together with the SKP1-like protein ASK1 to form a ubiquitin E3 ligase complex and could indirectly promote the ubiquitination and degradation of specific proteins controlling the floral primordia development like repressors of B class floral homeotic genes.
