Function
Involved in ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:24563205). Associates with the CDD complex and mediates the recognition of specific substrates for CUL4-RING E3 ubiquitin ligase (CRL4) by interacting with ubiquitination targets (PubMed:24563205). Binds to the abscisic acid (ABA) receptor PYL8 (required for ABA-mediated responses) and promotes its proteasomal degradation (PubMed:24563205). Acts as negative regulator of ABA-mediated developmental responses, including inhibition of seed germination, seedling establishment, and root growth (PubMed:24563205).
