MyBioSource.com's ARL3 Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: Immunohistochemistry, and Western Blot. The ARL3 Antibody was generated using ARL3 as the antigen and it reacts with Human, Mouse, and Rat.
Description
Function: Small GTP-binding protein which cycles between an inactive GDP-bound and an active GTP-bound form, and the rate of cycling is regulated by guanine nucleotide exchange factors (GEF) and GTPase-activating proteins (GAP). Required for normal cytokinesis and cilia signaling. Requires assistance from GTPase-activating proteins (GAPs) like RP2 and PDE6D, in order to cycle between inactive GDP-bound and active GTP-bound forms. Required for targeting proteins such as NPHP3 to the ciliary membrane by releasing myristoylated NPHP3 from UNC119B cargo adapter into the cilium. Does not act as an allosteric activator of the cholera toxin catalytic subunit.
Subunit Structure: Interacts with RP2. The GTP-bound form interacts with PDE6D. Found in a complex with ARL3, RP2 and UNC119 (or UNC119B); RP2 induces hydrolysis of GTP ARL3 in the complex, leading to the release of UNC119 (or UNC119B). Interacts with SYS1. The GTP-bound form interacts with ARL2BP and PDE6D. Interacts with RP2; interaction is direct and stimulated with the activated GTP-bound form of ARL3. Microtubule-associated protein. Does not interact with TBCC. May interact with GOLGA4.
Similarity: Belongs to the small GTPase superfamily. Arf family
