Protein attributes

Sequence length	328 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

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 for efficient protein synthesis during temperature stress conditions.
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Part of a SCF (ASK-cullin-F-box) protein ligase complex. Interacts with SKP1A/ASK1, SKP1B/ASK2, ASK4, ASK11 and ASK14.
Subcellular location	Nucleus. Mitochondrion. Ref.6
Tissue specificity	Expressed in leaves, flowers and stems, and, to a lower extent, in roots and siliques. Ref.6
Developmental stage	In seedlings, mostly localized in shoot meristems, root tips and hypocotyl. In adult plant, strongest levels observed in the vasculature, pollen, pollen tubes, and trichomes. Also found in senescencing leaves. Ref.6
Induction	By temperature stresses. Ref.6
Domain	The F-box is necessary for the interaction with ASK proteins By similarity.
Sequence similarities	Contains 1 F-box domain.
