Function

E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and transfers it to its substrates (PubMed:10373495, PubMed:16772533, PubMed:19204938, PubMed:19233847, PubMed:19325566, PubMed:19591933, PubMed:22645313, PubMed:24273172, PubMed:24728990, PubMed:30020076). Several substrates have been identified including the BMAL1, ARC, LAMTOR1, RAD23A and RAD23B, MCM7 (which is involved in DNA replication), annexin A1, the PML tumor suppressor, and the cell cycle regulator CDKN1B (PubMed:10373495, PubMed:19204938, PubMed:19325566, PubMed:19591933, PubMed:22645313, PubMed:24728990, PubMed:30020076). Additionally, may function as a cellular quality control ubiquitin ligase by helping the degradation of the cytoplasmic misfolded proteins (PubMed:19233847). Finally, UBE3A also promotes its own degradation in vivo. Plays an important role in the regulation of the circadian clock: involved in the ubiquitination of the core clock component BMAL1, leading to its proteasomal degradation (PubMed:24728990). Acts as transcriptional coactivator of progesterone receptor PGR upon progesterone hormone activation (PubMed:16772533). Acts as a regulator of synaptic development by mediating ubiquitination and degradation of ARC (By similarity). Required for synaptic remodeling in neurons by mediating ubiquitination and degradation of LAMTOR1, thereby limiting mTORC1 signaling and activity-dependent synaptic remodeling (By similarity). Synergizes with WBP2 in enhancing PGR activity (PubMed:16772533). (Microbial infection) Catalyzes the high-risk human papilloma virus E6-mediated ubiquitination of p53/TP53, contributing to the neoplastic progression of cells infected by these viruses.

Activity summary

UBE3A also known as ubiquitin protein ligase E3A is an enzyme with a molecular mass of approximately 100 kDa. It plays a central role in the ubiquitination process by adding ubiquitin to specific substrate proteins. UBE3A is found in many tissues but has high expression levels in the brain especially in neurons. The proper function of UBE3A requires its interaction with the ubiquitin-conjugating enzyme E2 marking target proteins for proteasomal degradation or other cellular processes.

Biological function summary

The role of UBE3A is connected to protein homeostasis and turnover. It is part of the ubiquitin-proteasome system which regulates the degradation of damaged or unneeded proteins. UBE3A does not work alone; it functions as part of a larger E3 ligase complex. This complex selectively identifies and modifies proteins determining their fate within the cell. The precision of UBE3A in these processes is necessary for normal neural development and synaptic plasticity.

Pathways

UBE3A is involved in the synaptic transmission and neuronal signaling pathways. It interacts with proteins such as HERC2 and RAD18 which are involved in DNA damage response and repair. UBE3A's involvement in these pathways highlights its importance in maintaining neuronal health. This protein’s activity influences downstream signaling events affecting processes like synaptic function and neuronal communication.

Associated diseases and disorders

Disruptions in UBE3A activity link to Angelman syndrome and autism spectrum disorders. Angelman syndrome results from the loss of function of the maternal UBE3A gene leading to severe neurological impairments. UBE3A's relationship with proteins like MECP2 involved in gene regulation suggests a broader role in neurodevelopmental disorders. Research continues to explore how UBE3A and its interaction partners contribute to the underlying mechanisms of these diseases.
