CC -!- FUNCTION: Has E2-dependent E3 ubiquitin-protein ligase activity.
CC Responsible for ubiquitination of cAMP-dependent protein kinase type I
CC and type II-alpha/beta regulatory subunits and for targeting them for
CC proteasomal degradation. Essential for PKA-mediated long-term memory
CC processes (PubMed:21423175). Through the ubiquitination of MFHAS1,
CC positively regulates the TLR2 signaling pathway that leads to the
CC activation of the downstream p38 and JNK MAP kinases and promotes the
CC polarization of macrophages toward the pro-inflammatory M1 phenotype.
CC Plays a role in ciliogenesis by ubiquitinating OFD1 (By similarity).
CC {ECO:0000250|UniProtKB:O43164, ECO:0000269|PubMed:21423175}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27; Evidence={ECO:0000250|UniProtKB:O43164};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000250|UniProtKB:O43164}.
CC -!- SUBUNIT: Binds ubiquitin-conjugating enzymes (E2s). In vitro, interacts
CC with the ubiquitin-conjugating enzyme, UBE2D2. The phosphorylated form
CC interacts with PRKAR1A, PRKAR2A and PRKAR2B. Binds the catalytic
CC subunits of cAMP-dependent protein kinase. Interacts with MFHAS1.
CC Interacts with TBC1D31; the interaction is direct and recruits PJA2 to
CC centrosomes. {ECO:0000250|UniProtKB:O43164}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:7623148}. Cell
CC membrane {ECO:0000250|UniProtKB:O43164}. Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:7623148}; Peripheral membrane protein
CC {ECO:0000269|PubMed:7623148}. Golgi apparatus membrane
CC {ECO:0000269|PubMed:7623148}; Peripheral membrane protein
CC {ECO:0000269|PubMed:7623148}. Synapse {ECO:0000269|PubMed:7623148}.
CC Postsynaptic density {ECO:0000269|PubMed:7623148}. Cytoplasm,
CC cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000250|UniProtKB:O43164}. Note=Localizes at the cytoplasmic side
CC of endoplasmic reticulum and Golgi apparatus (By similarity). Expressed
CC in the postsynaptic density region of synapses (PubMed:7623148).
CC Colocalizes with PRKAR2A and PRKAR2B in the cytoplasm and the cell
CC membrane (By similarity). {ECO:0000250|UniProtKB:O43164,
CC ECO:0000269|PubMed:7623148}.
CC -!- TISSUE SPECIFICITY: Highly expressed in the brain, in nerve cells but
CC not in glial cells. Abundantly expressed in pyramidal neurons and in
CC the CA3 region of apical dendrites. Colocalizes with PRKAR2B in dentate
CC granule cells and at postsynaptic sites of primary hippocampal neurons.
CC {ECO:0000269|PubMed:21423175, ECO:0000269|PubMed:7623148}.
