Protein Structure

UniProt Annotation

Function

Has E2-dependent E3 ubiquitin-protein ligase activity. Responsible for ubiquitination of cAMP-dependent protein kinase type I and type II-alpha/beta regulatory subunits and for targeting them for proteasomal degradation. Essential for PKA- mediated long-term memory processes. {ECO:0000269PubMed:12036302, ECO:0000269PubMed:21423175}.
