Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0002421
UniProt IDP15153
Primary gene name(s)RAC2
Synonym gene name(s)unknown
Protein nameRas-related C3 botulinum toxin substrate 2
Protein functionPlasma 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 secretory processes, phagocytose of apoptotic cells and epithelial cell polarization. Augments the production of reactive oxygen species, ROS by NADPH oxidase. {ECO:0000269|PubMed:1660188}.
Subcellular locationCytoplasm. Note=Membrane-associated when activated.
