Overview

Show »« Hide

The Rab family of proteins is a member of the Ras superfamily of monomeric G proteins. Rab GTPases regulate many steps of membrane traffic, including vesicle formation, vesicle movement along actin and tubulin networks, and membrane fusion. These processes make up the route through which cell surface proteins are trafficked from the Golgi to the plasma membrane and are recycled. Surface protein recycling returns proteins to the surface whose function involves carrying another protein or substance inside the cell, such as the transferrin receptor, or serves as a means of regulating the number of a certain type of protein molecules on the surface ( see HGNC RAB, 65 genes ).

Target Id	3292
Nomenclature	RAB32, member RAS oncogene family
Genes	RAB32 (Hs), Rab32 (Mm), Rab32 (Rn)
Ensembl ID	ENSG00000118508 (Hs), ENSMUSG00000019832 (Mm), ENSRNOG00000014258 (Rn)
UniProtKB AC	Q13637 (Hs), Q3TXU7 (Mm)
Comment	A genetic variant encoding a S71R substitution in the RAB32 small GTPase has been identified as a risk factor in familial Parkinson's disease [3]. RAB32^S71R appears to increase leucine rich repeat kinase 2 (LRRK2) autophosphorylation and kinase activity. Activating mutations in LRRK2 are already known to be associated with the pathobiology of the disease [1-2,6], with pharmacological inhibitors of LRRK2 being evaluated for clinical potential [5].
