The p21 RAS subfamily of small GTPases, including KRAS, HRAS, and NRAS, regulates cell proliferation, cytoskeletal organization, and other signaling networks, and is the most frequent target of activating mutations in cancer. Activating germline mutations of KRAS and HRAS cause severe developmental abnormalities leading to Noonan, cardio-facial-cutaneous, and Costello syndrome, but activating g...
Altered expression of the Fas-Fas ligand apoptotic pathway leads to lymphoproliferative and autoimmune diseases. In lpr/lpr mice and children with autoimmune lymphoproliferative syndrome, defective apoptosis is due to Fas mutations. Large granular lymphocyte (LGL) leukemia is a clonal lymphoproliferative disorder associated with rheumatoid arthritis. Leukemic LGLs are resistant to Fas-dependent...
MRL-lpr/lpr mice have a Fas receptor mutation that leads to abnormalities of apoptosis, lymphoproliferation, and a lupus-like autoimmune disease associated with the production of autoantibodies. Other than Fas pathway defects, little is known about molecular abnormalities that predispose to autoimmunity. Protein kinase CK2 (also termed casein kinase II), a serine-threonine protein kinase whose ...
