Protein attributes

Sequence length	628 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(EBF1) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (probably including EIN3 and EIL1). Regulator of the ethylene signaling cascade by modulating the stability of EIN3 and EIL1 proteins. Confers insensitivity to ethylene.
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Part of a SCF (SKP1-cullin-F-box) protein ligase complex. Interacts with CUL1, SKP1A/ASK1, SKP1B/ASK2, EIN3, and EIL1.
Subcellular location	Nucleus.
Tissue specificity	Ubiquitous.
Induction	EIN3-dependent induction by ethylene.
Sequence similarities	Contains 1 F-box domain. Contains 16 LRR (leucine-rich) repeats.
