DescriptionAnti-Aggrecan Antibody, MMP Cleaved, NT FFGVG neoepitopes, clone AF-28
Background InformationAggrecan is also known as aggregating chondroitin sulphate proteoglycan. Aggrecan is the major proteoglycan present in articular cartilage, composing up to 10% of its dry weight. It is responsible for endowing articular with its intrinsic properties of load bearing and compressive forces.

SpecificityMouse anti-aggrecan is a cleavage-site-specific monoclonal antibody for detecting metalloproteinase-derived aggrecan fragments. The antibody recognizes neo-epitopes on polypeptides with N-terminal FFGVG sequences. This sequence is found at the N-terminus of aggrecan fragments that have been digested with MMPs. By immunoblotting, AF-28 specifically detected G2 fragments derived from an aggrecan G1-G2 substrate digested with stromelysin, collagenase, gelatinase, and matrilysin, but failed to detect G2 fragments obtained from elastase, trypsin, or cathepsin B digests. Undigested G1-G2 was not detected. Competition experiments confirmed that peptides containing internal FFGVG sequences were not detected by the antibody. Clone AF-28 specifically recognizes a neo-epitope on polypeptides with N-terminal FFGVG Sequences. This sequence is found at the N-terminus of aggrecan fragments that have been digested with matrix metalloproteinases.

Entrez Gene Number
Entrez Gene SummaryThis gene is a member of the aggrecan/versican proteoglycan family. The encoded protein is an integral part of the extracellular matrix in cartilagenous tissue and it withstands compression in cartilage. Mutations in this gene may be involved in skeletal dysplasia and spinal degeneration. Multiple alternatively spliced transcript variants that encode different protein isoforms have been observed in this gene.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P16112 # This proteoglycan is a major component of extracellular matrix of cartilagenous tissues. A major function of this protein is to resist compression in cartilage. It binds avidly to hyaluronic acid via an N-terminal globular region.
SIZE: 2415 amino acids; 250193 Da
SUBUNIT: Interacts with FBLN1 (By similarity).
SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix (By similarity).
TISSUE SPECIFICITY: Restricted to cartilages.
DEVELOPMENTAL STAGE: Expression was detected in chondrocytes throughout the developing skeleton.
DOMAIN: SwissProt: P16112 Two globular domains, G1 and G2, comprise the N-terminus of the proteoglycan, while another globular region, G3, makes up the C-terminus. G1 contains Link domains and thus consists of three disulfide-bonded loop structures designated as the A, B, B' motifs. G2 is similar to G1. The keratan sulfate (KS) and the chondroitin sulfate (CS) attachment domains lie between G2 and G3.
PTM: Contains mostly chondroitin sulfate, but also keratan sulfate chains, N-linked and O-linked oligosaccharides. The release of aggrecan fragments from articular cartilage into the synovial fluid at all stages of human osteoarthritis is the result of cleavage by aggrecanase.
DISEASE: SwissProt: P16112 # Defects in AGC1 are the cause of spondyloepiphyseal dysplasia type Kimberley (SEDK) [MIM:608361]. Spondyloepiphyseal dysplasias are a heterogeneous group of congenital chondrodysplasias that specifically affect epiphyses and vertebrae. The autosomal dominant SEDK is associated with premature degenerative arthropathy.
SIMILARITY: Belongs to the aggrecan/versican proteoglycan family. & Contains 1 C-type lectin domain. & Contains 1 EGF-like domain. & Contains 1 Ig-like V-type (immunoglobulin-like) domain. & Contains 4 Link domains. & Contains 1 Sushi (CCP/SCR) domain.
