GIT1 Antibody (924640) [Unconjugated]

Western blot shows lysates of HUVEC human umbilical vein endothelial cells, U2OS human osteosarcoma cell line, M1 mouse myeloid leukemia cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human GIT1 Monoclonal Antibody (Catalog # MAB8508) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for GIT1 at approximately 95 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

GIT1 was detected in immersion fixed paraffin-embedded sections of human brain (hippocampus) using Mouse Anti-Human GIT1 Monoclonal Antibody (Catalog # MAB8508) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to neurons.

SH‑SY5Y human neuroblastoma cell line was stained with Mouse Anti-Human GIT1 Monoclonal Antibody (Catalog # MAB8508, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Recombinant Human GIT1 protein was serially diluted 2-fold and captured by Mouse Anti-Human/Mouse/Rat GIT1 Monoclonal Antibody (Catalog # MAB8508) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human GIT1 Monoclonal Antibody (Catalog # MAB85081) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background

GIT1 (ARF GTPase-activating protein GIT1) is a 95 kDa protein that belongs to ADP ribosylation factor family and is localized to focal adhesions, cytoplasmic complexes and membrane protrusions, and regulates cell protrusion formation and cell migration. 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. GIT1 has also been implicated in neuronal functions including synapse formation and the pathology of Huntington disease. Huntington disease is a genetic neurodegenerative condition involving a mutation in the huntington gene. The huntington gene product (htt) is ubiquitinated and degraded in human Huntington disease brains. Htt interacts directly with GIT1 causing enhanced htt proteolysis, indicating that GIT1 distribution and function may contribute to Huntington disease pathology. Within amino acids (aa) 485-636, human and mouse GIT1 share 93% aa sequence identity.
