Mains targets of ABC(E)genes

Protein function

Encodes a component of the E3 ubiquitin ligase complex.


UFO overexpression causes several floral defects, including supernumerary petals and stamens. [Lee et al., 1997]

Single mutant:
ufo single mutant has multiple floral defects. [Wilkinson et al., 1995][Samach et al., 1999][Levin et al., 1995][Ingram et al., 1995]

UFO is an upstream regulator of AP3 expression and is therefore involved in floral meristem determinacy. [Lee et al., 1997]

Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). 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.
