RASIP1 polyclonal antibody

RAIN, also known as RASIP1 (Ras-interacting protein 1), is a 963 amino acid protein that contains one dilute domain and one Ras-associating domain. The RAIN protein is highly expressed in heart and detected at lower levels in placenta and pancreas. RAIN interacts with H-Ras, Rap 1A, Rap 2, R-Ras, Raf-1 and TC 21, as well as with Ras family members that have been activated by GTP binding. RAIN interacts with Ras in a GTP-dependent manner in vitro and in vivo, requiring an intact Ras core effector-binding domain for this interaction, and thus fits the definition of a Ras effector. Unlike other Ras effectors, RAIN localizes to the perinuclear, juxta-Golgi vesicles in intact cells and is recruited to the Golgi by activated Ras. Containing twelve exons, the RAIN gene is conserved in dog, cow, mouse, rat, chicken and zebrafish, and maps to human chromosome 19q13.33.
