  • Western blot analysis of extracts from Jurkat (lane 2(20μg), Jurkat (lane 3(40μg), using CD79a Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

  • Immunocytochemistry analysis of Hela cells labeling CD79a with CD79a Antibody (HY-P80606) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with CD79a Antibody (HY-P80606) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
Function: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
Subcellular Localization:Cell membrane; Single-pass type I membrane protein
Expression:
Tissue_specificity:B cells
Isoforms & Post-Translational Modification:P11912 has 2 isomers: P11912-1: 25038 Da (predicted); P11912-2: 20786 Da (predicted).
Phosphorylated on tyrosine, serine and threonine residues upon B-cell activation. Phosphorylation of tyrosine residues by Src-family kinases is an early and essential feature of the BCR signaling cascade. The phosphorylated tyrosines serve as docking sites for SH2-domain containing kinases, leading to their activation which in turn leads to phosphorylation of downstream targets. Phosphorylated by LYN. Phosphorylation of serine and threonine residues may prevent subsequent tyrosine phosphorylation;Arginine methylation in the ITAM domain may interfere with the binding of SYK. It promotes signals leading to B-cell differentiation (By similarity)
Subunit:Heterodimer of alpha and beta chains; disulfide-linked.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
