Catalog No. ABIN7317991

Product Details

Target: COMP (Cartilage Oligomeric Matrix Protein (COMP))

Protein Type: Recombinant

Biological Activity: Active

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This COMP protein is labelled with His tag.

Purpose: Recombinant Human COMP Protein (His Tag)(Active)

Sequence: Met 1-Ala 757

Characteristics: A DNA sequence encoding the human COMP (NP_000086.2) precusor (Met 1-Ala 757) was expressed with a C-terminal polyhistidine tag.

Purity: > 95 % as determined by reducing SDS-PAGE.

Endotoxin Level: < 1.0 EU per μg as determined by the LAL method.

Biological Activity Comment: Measured by its ability to induce adhesion of ATDC5 mouse chondrogenic cells. When cells are added to coated plates (5 μg/ml, 100 μl/well), approximately 40% will adhere specifically after 60 minutes at 37 °C.

Background:

Background: Cartilage Oligomeric Matrix Protein (COMP), also referred to as Thrombospondin-5, is a non-collagenous extracellular matrix (ECM) protein and belongs to the subgroup B of the thrombospondin protein family. This protein is expressed primarily in cartilage, ligament, and tendon, and binds to other ECM proteins such as collagen I, II and IX with high affinities depending on the divalent cations Zn2+ or Ni2+. COMP is a secreted glycoprotein that is important for growth plate organization and function. It is suggested to play a role in cell growth and development, and recent studies have revealed the possible mechanism that it protects cells against death by elevating members of the IAP (inhibitor of apoptosis protein) family of survival proteins. Mutations in COMP cause two skeletal dysplasias, pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (EDM1), and up-regulated expression of COMP are observed in rheumatoid arthritis and certain carcinomas.
