Mannose-6-phosphate receptor binding protein 1 (M6PRBP1) is a protein which in humans is encoded by the M6PRBP1 gene.^[5] Its gene product, as well as the gene itself, is commonly known as TIP47.

Function[edit]

Mannose 6-phosphate receptors (MPRs) deliver lysosomal hydrolase from the Golgitoendosomes 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]

TIP47 belongs to the peripilin protein family and shares significant homology with the other genes of this family, including perilipin and adipophilin.^[9]

Interactions[edit]

M6PRBP1 has been shown to interact with both Mannose 6-phosphate receptors.^[10][11]
