General annotation (Comments)

Function	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. Required during the endosperm development in embryos.
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Part of a SCF (ASK-cullin-F-box) protein ligase complex By similarity. Interacts with SKP1A/ASK1 and CUL1.
Domain	The F-box is necessary for the interaction with ASK proteins By similarity.
Sequence similarities	Contains 1 F-box domain.
