Scientific Data Images for Human/Mouse BCAP Antibody

Detection of Human BCAP by Western Blot.

Western Blot shows lysates of RL human non-Hodgkin's lymphoma B cell line and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/ml of Goat Anti-Human/Mouse BCAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4857) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). Specific bands were detected for BCAP at approximately 80 kDa and 100 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.
Detection of Human BCAP/PIK3AP1 by Western Blot

Detection of Human BCAP/PIK3AP1 by Western Blot

BCAP is hyperphosphorylated in B-cell, macrophages, and Expi293F cells.A, lysates from THP-1 and Ramos cells were dephosphorylated with lambda -phosphatase and immunoblotted for BCAP. B, His-Avi-tagged BCAP expressed in Expi293F cells was purified and dephosphorylated with lambda -phosphatase before immunostaining for tyrosine and serine phosphorylation. C, phosphorylation sites of BCAP expressed in Expi293F cells were determined by phosphopeptide mapping. BCAP was digested with trypsin, chymotrypsin, Asp-N, and Glu-C prior to MS.

Detection of Human BCAP/PIK3AP1 by Western Blot

BCAP is phosphorylated by BTK, LYN, and SYK. Purified BCAP, dephosphorylated BCAP ( lambda -BCAP), and myelin basic protein (MyBP) were phosphorylated with (A) tyrosine kinases SYK, LYN, BTK, TYK2, and ITK, or (B) serine kinases CSNK1A1, CSNK2A2, and GSK-3.

Background: BCAP

BCAP (B-cell adaptor for phosphoinositide 3-kinase (PI3K)) participates in linking the B cell antigen receptor (BCR) with the PI3K pathway. Tyrosine phosphorylation of BCAP by BCR-associated protein tyrosine kinases, such as Syk and Btk, generates binding sites for the p85 subunit of PI3K, resulting in activation of the PI3K pathway. Human and mouse BCAP contain 3 YXXM SH2 binding motifs for interaction with PI3K.
