Other Names | B-cell linker protein, B-cell adapter containing a SH2 domain protein, B-cell adapter containing a Src homology 2 domain protein, Cytoplasmic adapter protein, Src homology 2 domain-containing leukocyte protein of 65 kDa, SLP-65, BLNK, BASH, SLP65 |
Target/Specificity | The synthetic peptide sequence used to generate the antibody AP13433a was selected from the N-term region of BLNK. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay. |
Format | Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed. |
Storage | Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C. |
Precautions | This product is for research use only. Not for use in diagnostic or therapeutic procedures. |
Name | BLNK |

Synonyms | BASH, SLP65 |
Function | Functions as a central linker protein, downstream of the B- cell receptor (BCR), bridging the SYK kinase to a multitude of signaling pathways and regulating biological outcomes of B-cell function and development. Plays a role in the activation of ERK/EPHB2, MAP kinase p38 and JNK. Modulates AP1 activation. Important for the activation of NF-kappa-B and NFAT. Plays an important role in BCR- mediated PLCG1 and PLCG2 activation and Ca(2+) mobilization and is required for trafficking of the BCR to late endosomes. However, does not seem to be required for pre-BCR-mediated activation of MAP kinase and phosphatidyl-inositol 3 (PI3) kinase signaling. May be required for the RAC1-JNK pathway. Plays a critical role in orchestrating the pro-B cell to pre-B cell transition. May play an important role in BCR- induced B-cell apoptosis. |
Cellular Location | Cytoplasm. Cell membrane. Note=BCR activation results in the translocation to membrane fraction |
Tissue Location | Expressed in B-cell lineage and fibroblast cell lines (at protein level). Highest levels of expression in the spleen, with lower levels in the liver, kidney, pancreas, small intestines and colon |

Background
This gene encodes a cytoplasmic linker or adaptor proteinthat plays a critical role in B cell development. This proteinbridges B cell receptor-associated kinase activation withdownstream signaling pathways, thereby affecting various biologicalfunctions. The phosphorylation of five tyrosine residues isnecessary for this protein to nucleate distinct signaling effectorsfollowing B cell receptor activation. Mutations in this gene causehypoglobulinemia and absent B cells, a disease in which the pro- topre-B-cell transition is developmentally blocked. Deficiency inthis protein has also been shown in some cases of pre-B acutelymphoblastic leukemia. Alternatively spliced transcript variantsencoding different isoforms have been found for this gene.
