Previous GeneCards Identifiers for RAC3 Gene
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. [provided by RefSeq, Oct 2015]
GeneCards Summary for RAC3 Gene
RAC3 (Rac Family Small GTPase 3) is a Protein Coding gene. Among its related pathways are PAK Pathway and Beta-Adrenergic Signaling. Gene Ontology (GO) annotations related to this gene include GTP binding and calcium-dependent protein binding. An important paralog of this gene is RAC1.
UniProtKB/Swiss-Prot for RAC3 Gene
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.
Small G proteins (small GTPases) are homologous to Galpha proteins and are often referred to as the Ras proto-oncogene superfamily. Small GTPases regulate a wide variety of processes in the cell, including growth, differentiation, movement and lipid vesicle transport.
