PRG4 - proteoglycan 4 Gene
Also Known as MSF; SZP; CACP; HAPO; JCAP
Species: Homo sapiens
About PRG4
This gene has 6 transcripts (splice variants), 247 orthologues, 1 paralogue and is associated with 2 phenotypes. Biased expression in liver (RPKM 61.2), fat (RPKM 6.6) and 1 other tissue.
Summary
The protein encoded by this gene is a large proteoglycan that is synthesized by chondrocytes located at the surface of articular cartilage and by some synovial lining cells. This protein contains both chondroitin sulfate and keratan sulfate glycosaminoglycans. It functions as a boundary lubricant at the cartilage surface and contributes to the elastic absorption and energy dissipation of synovial fluid. Mutations in this gene result in camptodactyly-arthropathy-coxa vara-pericarditis syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]
