Protein: E3 ubiquitin-protein ligase AIP2 (EC 2.3.2.27) (ABI3-interacting protein 2) (RING-type E3 ubiquitin transferase AIP2) (Q8RXD3)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: E3 ubiquitin-protein ligase that acts as a negative regulator of abscisic acid (ABA) signaling. Mediates ubiquitination and subsequent proteasomal degradation of the transcription factor ABI3.
