  • 蛋白标签：
    N-terminal 10xHis-tagged
  • 产品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.

靶点详情

  • 功能：
    Required in cooperation with CD79B for initiation of the signal transduction cascade activated by binding of antigen to the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Also required for BCR surface expression and for efficient differentiation of pro- and pre-B-cells. Stimulates SYK autophosphorylation and activation. Binds to BLNK, bringing BLNK into proximity with SYK and allowing SYK to phosphorylate BLNK. Also interacts with and increases activity of some Src-family tyrosine kinases. Represses BCR signaling during development of immature B-cells.

    1. The incidence of MYD88 and CD79B mutations in patients with CD5(+) DLBCL is lower than that in patients with DLBCL-SS, suggesting that CD5(+) DLBCL is not the same disease as DLBCL-SS in terms of gene mutation status. PMID: 27915469
    2. Phosphorylation of CD79a causes a decrease in helical propensity in the C-terminal region, for CD79b, the opposite was observed and phosphorylation resulted in an increase of helical propensity in the C-terminal part. PMID: 24769851
    3. High intensity of caries is associated with increased levels of some salivary components - sIgA, histatin-5 and lactoperoxidase. PMID: 24974109
    4. CD79a plays a functional role in the tumor promoting effects of myeloid cells, and may represent a novel target for cancer therapy. PMID: 24146823

    7. Unlike the B29 octamer motif, the mb-1 octamer motif does not have the essential sequence required for OBF-1/Bob1 interaction, therefore its promoter is not transactivated by OBF-1/Bob1. PMID: 11907094

    9. There is a somatic hypermutation of this gene in B-cell lymphoma and multiple myeloma. PMID: 12651942
    10. Results indicate that PAX5 is a more specific marker than CD79a for B-cell ALL diagnosis. PMID: 15492262
    11. lower levels of B-cell receptor surface expression observed in chronic lymphocytic leukemia are accounted for by an impaired glycosylation and folding of the mu and CD79a chains. PMID: 15591116
    12. FISH findings indicate that CD79a, despite its specificity for B-cell differentiation, represented the aberrant presence of a B-cell antigen in leukemias of distinct myeloid linage. PMID: 16271957
    13. Acute leukemia with t(8;21) coexpresses CytCD79a represent biphenotypic acute leukemia. PMID: 17350472
    14. Anti-CD79b antibodies downregulated surface B-cell receptor and were trafficked to the lysosomal-like major histocompatibility complex class II-positive compartment of a mouse xenograft model of non-Hodgkin lymphoma. PMID: 17374736
    15. Ig-alpha was phosphorylated in all myeloma IgG BCR isolates, the 31-kD variant being phosphorylated most frequently. It was not phosphorylated in normal control B cells. PMID: 17701175
    16. Median survival time of cytoplasmic CD79 alpha positive group was shorter than that of cytCD79a negative group in acute myeloid leukemia. PMID: 18160827
