Recombinant Human Ras-related C3 botulinum toxin substrate 3 (RAC3)

Uniprot Id

P60763

Target Species

Human

Target Name

RAC3

Target Full Name

Ras-related C3 botulinum toxin substrate 3

Target Function

Plasma membrane-associated small GTPase which cycles between an active GTP-bound and inactive GDP-bound state. In active state binds to a variety of effector proteins to regulate cellular responses, such as cell spreading and the formation of actin-based protusions including lamellipodia and membrane ruffles. Promotes cell adhesion and spreading on fibrinogen in a CIB1 and alpha-IIb/beta3 integrin-mediated manner.

Target Subcellular Location

Cytoplasm. Endomembrane system. Cell projection, lamellipodium. Cytoplasm, perinuclear region. Cell membrane. Cytoplasm, cytoskeleton. Note=Membrane-associated when activated. Colocalizes with NRBP to endomembranes and at the cell periphery in lamellipodia. Colocalized with CIB1 in the perinuclear area and at the cell periphery.

Target Protein Families

Small GTPase superfamily, Rho family

Target Tissue Specificity

Highest levels in brain, also detected in heart, placenta and pancreas.

Target Research Area

Signal Transduction

Target Background

The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Alternative splicing results in multiple transcript variants.
