GIT1 Antibody [N39B/8 (Formerly sold as S39B-8)] is a mouse monoclonal antibody directed against GIT1, offered by Assay Genie for research applications. Reported applications include WB, ICC/IF and IP. Reported reactivity: Human, Mouse and Rat. Supplied as IgG1, purified by Protein G.
GIT1 (G-protein-coupled receptor kinase-interacting protein 1) is a highly conserved scaffold protein that plays a central role in coordinating intracellular signaling, cytoskeletal remodeling, and cell migration. It contains multiple interaction domains that enable binding to small GTPases (such as ARF, Rac, and Cdc42), kinases (including PAK and MEK), the Rho-family GEF PIX, and the focal adhesion protein paxillin. Through these interactions, GIT1 regulates focal adhesion dynamics and membrane protrusion formation. In the nervous system, GIT1 is enriched at synapses and is essential for synapse formation, dendritic spine morphogenesis, and synaptic plasticity. Its localization to cytoplasmic complexes and membrane structures supports its role in neuronal signaling and structural remodeling. Importantly, GIT1 has been implicated in the pathogenesis of Huntington’s disease (HD), a neurodegenerative disorder caused by mutations in the huntingtin (HTT) gene. GIT1 directly interacts with mutant HTT, enhancing its proteolysis and potentially contributing to the accumulation of toxic protein fragments. This interaction suggests that altered GIT1 distribution or function may exacerbate neuronal dysfunction and degeneration in HD. Given its dual role in cytoskeletal regulation and synaptic signaling, GIT1 is emerging as a critical molecular player in neurodegenerative disease research. Understanding its mechanisms may reveal novel therapeutic targets for modulating synaptic integrity and mitigating disease progression. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg. For research use only; not for diagnostic or therapeutic procedures.
