Background

G protein-coupled receptor (GPCR) kinase interacting proteins 1 and 2 (GIT1 and GIT2) are highly conserved, ubiquitous scaffold proteins involved in localized signaling to help regulate focal contact assembly and cytoskeletal dynamics. GIT proteins contain multiple interaction domains that allow interaction with small GTPases (including ARF, Rac, and cdc42), kinases (such as PAK and MEK), the Rho family GEF PIX, and the focal adhesion protein paxillin (reviewed in 1). GIT1 is localized to focal adhesions, cytoplasmic complexes and membrane protrusions, and regulates cell protrusion formation and migration (2). GIT1 has also been implicated in neuronal functions including synapse formation (3) and the pathology of Huntington's disease (HD) (4). HD is a genetic neurodegenerative condition involving a mutation in the htt gene encoding the protein huntingtin. Huntingtin is ubiquitinated and degraded in human HD brains (5). Huntingtin interacts directly with GIT1, causing enhanced proteolysis and indicating that GIT1 distribution and function may contribute to HD pathology (4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

GIT1 (F5R4M) Rabbit mAb

Western Blotting Image 1: GIT1 (F5R4M) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using GIT1 (F5R4M) Rabbit mAb (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Lower expression of GIT1 protein in HCC1419 cells is consistent with the predicted expression pattern.
Immunoprecipitation Image 1: GIT1 (F5R4M) Rabbit mAb Expand Image
Immunoprecipitation of GIT1 protein from SCLC-21H cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is GIT1 (F5R4M) Rabbit mAb. Western blot analysis was performed using GIT1 (F5R4M) Rabbit mAb. Anti-rabbit IgG, HRP-linked Antibody #7074 was used as a secondary antibody.
