Research Abstract

RAPL, Rap1 binding protein, plays crucial roles in Rap1-dependent lymphocyte adhesion and migration. RAPL-deficient mice experienced age-related lupus-like glomerulonephritis and developed B cell lymphomas. RAPL promoted the nuclear localization of p27, cdk2 inhibitor, and prevented the hyperproliferation of both T and B lymphocytes induced by the crosslinking with the antibody to antigen receptors. These data demonstrated that lymphocyte adhesion and proliferation were coordinately regulated by RAPL, and the deficiency of such molecule solely led to the development of lymphoproliferative diseases.
