SPA-1 Antibody (B-7) is a mouse monoclonal IgM kappa light chain antibody that detects SPA-1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). SPA-1 (B-7) antibody is available as the non-conjugated form. SPA-1 (signal-induced proliferation-associated gene-1) protein serves as a crucial regulator in hematopoietic progenitors and peripheral T cells, functioning primarily as a RAP1 GTPase-activating protein. SPA-1 protein is predominantly expressed in fetal and adult lymphohematopoietic tissues, and SPA-1 expression is significantly upregulated in response to various mitogenic stimuli in normal lymphocytes. SPA-1 protein′s ability to disrupt LFA-1-ICAM1-mediated adhesive interactions is vital for modulating T cell receptor signaling and subsequent interleukin-2 production, potentially through RAP1 activity inhibition. SPA-1 protein also interacts directly with aquaporin-2 (AQP2), influencing AQP2 trafficking to the apical membrane, which is essential for maintaining water homeostasis in renal epithelial cells. Mice lacking SPA-1 gene exhibit age-dependent T cell immunodeficiency and develop late-onset myeloproliferative disorders, closely resembling human chronic myeloid leukemia, underscoring SPA-1 protein′s importance in immune regulation and cellular signaling pathways.
