| 背景 | B cell linker protein (BLNK), also known as SLP-65 or BASH, is an adaptor molecule that plays key roles in B cell activation and B cell antigen receptor (BCR) engagement. BLNK acts at the interface between BCR-associated Syk and downstream signaling cascades (1,2). BLNK has multiple SH2 binding motifs (YXXP) at its amino terminus and an SH2 domain at its carboxy terminus. After BCR ligation, BLNK is phosphorylated by Syk at multiple YXXP motifs including Tyr72, Tyr84, Tyr96, and Tyr178 (1). These phosphorylated motifs provide docking sites for signaling molecules, such as BTK, PLCγ, and Vav. These signaling molecules bind to BLNK through their SH2 domains and together activate downstream signaling pathways (3,4). Through its SH2 domain, BLNK can also interact with tyrosine-phosphorylated targets, such as HPK1, thereby recruiting them to the BCR complex for signaling (5). |

Western blot analysis of extracts from various cell lines using BLNK (D3P2H) XP® Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). BLNK protein expression is detected in B cell extracts as expected, but is not detected in Jurkat cell extracts. | |
Immunohistochemical analysis of paraffin-embedded human breast carcinoma using BLNK (D3P2H) XP® Rabbit mAb. | |
Immunohistochemical analysis of paraffin-embedded human tonsil using BLNK (D3P2H) XP® Rabbit mAb. | |
Immunohistochemical analysis of paraffin-embedded human lymphoma using BLNK (D3P2H) XP® Rabbit mAb in the presence of control peptide (left) or antigen-specific peptide (right). | |
Flow cytometric analysis of human whole blood using BLNK (D3P2H) XP® Rabbit mAb co-stained with CD19-APC (left) and CD3-PE (right). CD19+ B cells are positive for BLNK, whereas CD3+ T cells are negative. Analysis was performed on cells in the lymphocyte gate. Anti-rabbit IgG (H+L), F(ab)2 fragment (Alexa Fluor 488 conjugate) #4412 was used as secondary Ab. |
