InnateDB Annotation
RAC1 cooperates with TLR2, MyD88, and PI3K in lipoteichoic acid-induced cPLA2/COX-2-dependent airway inflammatory responses.
InnateDB Annotation from Orthologs
[Mus musculus] Cd81 inhibits Rac1/Stat1 activation and negatively regulates the defence mechanisms to Listeria monocytogenes infection.
Entrez Gene
Summary 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
