The gene RAB32 (Ras-related protein) is mapped to human chromosome 6q24.3. It is a Rab GTPase which is present in the mitochondria. The protein also has a transient phagosomal localization and is also present at the melanosome membrane.
Application
Anti-Rab32 antibody produced in rabbit has been used for western blotting and immunofluorescence.
Biochem/physiol Actions
RAB32 (Ras-related protein) controls intracellular lipid accumulation in hepatocytes. Absence of it promotes the expression of ATGL (adipose triglyceride lipase) and thereby causes lipolysis. RAB32 is involved in hepatic steatosis. In melanogenesis, it is involved in the transport of important enzymes, such as tyrosinase and Tyrp1 (tyrosinase related protein 1). RAB32 also interacts with and is involved in localization of leucine-rich repeat kinase 2 (LRRK2), a protein associated with Parkinson′s disease. RAB32 is hypermethylated in microsatellite-unstable colon, gastric and endometrial adenocarcinomas.
Rab32 facilitates mitochondrial anchoring of protein kinaseA (PKA) and mitochondrial dynamics. Rab32 was also found to be required for the formation of autophagic vacuoles.
