Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific.

Research Backgrounds

Q92954_PRG4_HUMAN

Function:

Plays a role in boundary lubrication within articulating joints. Prevents protein deposition onto cartilage from synovial fluid by controlling adhesion-dependent synovial growth and inhibiting the adhesion of synovial cells to the cartilage surface.

Isoform F plays a role as a growth factor acting on the primitive cells of both hematopoietic and endothelial cell lineages.

PTMs:

N-glycosylated.

O-glycosylated; contains glycosaminoglycan chondroitin sulfate and keratan sulfate. O-glycosylated with sialylated oligosaccharides which are predominantly represented by the monosialylated core type I structure, NeuNAcalpha2-3Galbeta1-3GalNAc, with smaller amounts of disialylated O-glycans.

The disulfide bond between Cys-1146 and Cys-1403 is essential for protein cleavage.

Subcellular Location:

Secreted.

Tissue Specificity:

Highly expressed in synovial tissue, cartilage and liver and weakly in heart and lung. Isoform B is expressed in kidney, lung, liver, heart and brain. Isoform C and isoform D are widely expressed.
