This gene encodes a member of the P-type lectin family. P-type lectins play a critical role in lysosome function through the specific transport of mannose-6-phosphate-containing acid hydrolases from the Golgi complex to lysosomes. The encoded protein functions as a homodimer and requires divalent cations for ligand binding. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome X. [provided by RefSeq, May 2011]

A study in mice demonstrated that the M6PR mRNA was down-regulated (0.12-fold) in bone marrow cells 6 hours after a 6.5 Gy whole-body ionizing radiation exposure [Dai et al. DOI:10.1080/09553000600857389].
