E3 ubiquitin-protein ligase MIB1 (MIB1), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 5-332aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: RNNRVMVEGV GARVVRGPDW KWGKQDGGEG HVGTVRSFES PEEVVVVWDN GTAANYRCSG AYDLRILDSA PTGIKHDGTM CDTCRQQPII GIRWKCAECT NYDLCTVCYH GDKHHLRHRF YRITTPGSER VLLESRRKSK KITARGIFAG ARVVRGVDWQ WEDQDGGNGR RGKVTEIQDW SASSPHSAAY VLWDNGAKNL YRVGFEGMSD LKCVQDAKGG SFYRDHCPVL GEQNGNRNPG GLQIGDLVNI DLDLEIVQSL QHGHGGWTDG MFETLTTTGT VCGIDEDHDI VVQYPSGNRW TFNPAVLTKA NIVRSGDAAQ GAEGGTSQ. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: E3 ubiquitin-protein ligase that mediates ubiquitination of Delta receptors, which act as ligands of Notch proteins. Positively regulates the Delta-mediated Notch signaling by ubiquitinating the intracellular domain of Delta, leading to endocytosis of Delta receptors. Probably mediates ubiquitination and subsequent proteasomal degradation of DAPK1, thereby antagonizing anti-apoptotic effects of DAPK1 to promote TNF-induced apoptosis . Involved in ubiquitination of centriolar satellite CEP131, CEP290 and PCM1 proteins and hence inhibits primary cilium formation in proliferating cells. Mediates 'Lys-63'-linked polyubiquitination of TBK1, which probably participates in kinase activation.1 Publication. Reference: Prediction of the coding sequences of unidentified human genes. XVI.

Positively regulates the Delta-mediated Notch signaling by ubiquitinating the intracellular domain of Delta, leading to endocytosis of Delta receptors. Probably mediates ubiquitination and subsequent proteasomal degradation of DAPK1, thereby antagonizing anti-apoptotic effects of DAPK1 to promote TNF-induced apoptosis (By similarity).
