PTPRCAP Antibody (17A5) is a mouse monoclonal IgG1 antibody that detects PTPRCAP protein of human origin by western blotting (WB), immunofluorescence (IF), and immunohistochemistry with paraffin-embedded sections (IHCP). Anti-PTPRCAP antibody (17A5) is available as the non-conjugated format. PTPRCAP protein, also known as protein tyrosine phosphatase, receptor type, C-associated protein, is a 206 amino acid single-pass membrane protein that plays a crucial role in the immune system by stabilizing the association of CD45, a vital regulator of T- and B-lymphocyte activation. This interaction is essential for modulating the threshold of T-cell activation, which is critical for an effective immune response. PTPRCAP is implicated in the activation of oncogenic Src family kinases, highlighting its importance in both normal immune function and potential pathological conditions. The regulation of protein tyrosine phosphorylation, which PTPRCAP is involved in, influences various cellular responses, including growth, differentiation, and survival, making PTPRCAP a significant target for research in immunology and cancer biology.
