Mannose-6-phosphate receptor binding protein 1 (M6PRBP1) is a
protein which in humans is encoded by the M6PRBP1gene.[5] Its gene product, as well as the gene itself, is commonly known as TIP47.
Function
Mannose 6-phosphate receptors (MPRs) deliver
lysosomalhydrolase from the
Golgi to
endosomes and then return to the Golgi complex. The protein encoded by this gene interacts with the cytoplasmic domains of both cation-independent and cation-dependent MPRs, and is required for endosome-to-Golgi transport. This protein also binds directly to the GTPase RAB9 (
RAB9A), a member of the
RAS oncogene family. The interaction with RAB9 has been shown to increase the affinity of this protein for its cargo.[6]
The mannose-6-phosphate receptor-binding properties of TIP47 are disputed,[7] despite the designation of M6PRBP1 as TIP47's gene symbol. TIP47 protein is most commonly described in the scientific literature as a coat protein for
lipid droplets.[8]
