Prg4 Gene Summary [Rat]
Predicted to enable polysaccharide binding activity and scavenger receptor activity. Predicted to be involved in immune response and vesicle-mediated transport. Predicted to act upstream of or within hematopoietic stem cell proliferation; negative regulation of interleukin-6 production; and regulation of cell population proliferation. Predicted to be active in collagen-containing extracellular matrix and extracellular space. Human ortholog(s) of this gene implicated in camptodactyly-arthropathy-coxa vara-pericarditis syndrome and pericarditis. Orthologous to human PRG4 (proteoglycan 4).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Prg4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- Hemopexin-like repeats
- Family of unknown function (DUF5585)
