  • 产品描述：

    The recombinant Mouse Ube3a protein is encoded by the gene of Ube3a (542-870aa). The gene of Ube3a was cloned in a system (Yeast) that supported the expression of Ube3a and translation of messenger RNA. Modification of Ube3a by recombinant DNA technology could lead to the expression of the target protein. The protein was fused with N-terminal 6xHis tag in the production. The purity is 90% determined by SDS-PAGE.

    Ube3a is a protein coding gene that encodes Ubiquitin-protein ligase E3A. According to some studies, Ube3a may have the following features.
    UBE3A/E6-AP mutations cause Angelman syndrome. Angelman syndrome protein Ube3A regulates synapse development through ubiquitination arcs. Ube3a is required for experience-dependent maturation of the neocortex. Ube3a-ATS is an atypical RNA polymerase II transcript that inhibits the paternal expression of Ube3a. An autism-linked mutation disables phosphorylation control of UBE3A. An alternative Ube3a transcript has a coding-independent function during neuronal development.

靶点详情

  • 功能：
    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. Several substrates have been identified including the ARNTL/BMAL1, ARC, RAD23A and RAD23B, MCM7 (which is involved in DNA replication), annexin A1, the PML tumor suppressor, and the cell cycle regulator CDKN1B. Additionally, may function as a cellular quality control ubiquitin ligase by helping the degradation of the cytoplasmic misfolded proteins. 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 ARNTL/BMAL1, leading to its proteasomal degradation. Acts as a regulator of synaptic development by mediating ubiquitination and degradation of ARC. Synergizes with WBP2 in enhancing PGR activity.
