{{Infobox_gene}}

ARF GTPase-activating protein GIT1 is an enzyme that in humans is encoded by the GIT1 gene.{{cite journal | vauthors = Premont RT, Claing A, Vitale N, Freeman JL, Pitcher JA, Patton WA, Moss J, Vaughan M, Lefkowitz RJ | title = beta2-Adrenergic receptor regulation by GIT1, a G protein-coupled receptor kinase-associated ADP ribosylation factor GTPase-activating protein | journal = Proc Natl Acad Sci U S A | volume = 95 | issue = 24 | pages = 14082–14087 | date = December 1998 | pmid = 9826657 | pmc = 24330 | doi = 10.1073/pnas.95.24.14082 | bibcode = 1998PNAS...9514082P | doi-access = free }}{{cite journal | vauthors = Premont RT, Claing A, Vitale N, Perry SJ, Lefkowitz RJ | title = The GIT family of ADP-ribosylation factor GTPase-activating proteins.

GIT1 contains an ARFGAP domain, Anykrin repeats, and a GRK-interacting domain. The Arf-GAP domain, which enables it to act as a GTPase activating protein (GAP) for the Arf family of GTPases, has been shown to be involved in phosphorylation and inhibition of the ADRB2. If synaptic localization of GIT1 is disturbed, then this is known to affect dendritic spine morphology and formation—this is thought to occur through the Rac1/PAK1/LIMK/CFL1 pathway.{{cite journal | vauthors = Zhang H, Webb DJ, Asmussen H, Horwitz AF | title = Synapse formation is regulated by the signaling adaptor GIT1 | journal = J.
