Protein function
Encodes an E3 ubiquitin ligase.
Phenotype
Overexpressor: AT-STUBL4 overexpressor is early flowering under both SD and LD conditions.
[Elrouby et al., 2013] Single mutant: at-stubl4 single mutant is late flowering under both SD and LD conditions.
[Elrouby et al., 2013] Remarks: AT-STUbl4 regulates the stability of CDF proteins, which are known to be involved in the repression of
CONSTANS expression.
[Elrouby et al., 2013] Function:E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. It probably triggers the ubiquitin-mediated degradation of different substrates (By similarity).
