KRAP interacts with IP₃R1 in the kidney and with IP₃R3 in the stomach. (A) Western blots showing comparable expression levels of IP₃R1 in the kidney (left) or of IP₃R3 in the stomach (right) between KRAP-deficient (KO) and wild-type (WT) mice. (B) Anti-KRAP (αKRAP) immunoprecipitations were performed using mouse kidneys and stomachs from WT or KO mice, followed by western blotting with anti-KRAP, anti-IP₃R1, or anti-IP₃R3 antibodies. total, total lysate;IP, immunoprecipitation; α, anti-.
