Protein attributes

Sequence length	628 AA.
Sequence status	Complete.
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. Ref.1
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, ASK11, ASK12, ASK13, ASK18, EIN3, and EIL1. Ref.1 Ref.8 Ref.9
Subcellular location	Nucleus Ref.1.
Tissue specificity	Ubiquitous. Ref.1
Induction	EIN3-dependent induction by ethylene. Ref.1
Domain	The F-box is necessary for the interaction with ASK proteins By similarity.
Sequence similarities	Contains 1 F-box domain.
