COMP
Oligomerni protein hrskavičnog matriksa (COMP), poznat i kao trombospondin-5, prvenstveno je protein vanćelijskog matriksa (ECM) prisutan u hrskavicama. Kod ljudi je kodiran je genom COMP.[5][6][7]

Funkcija
[uredi | uredi izvor]Protein koji je kodiran ovim genom je nekolageni vanćelijski matrikssni (ECM) protein.[8] Sastoji se od pet identičnih glikoproteinskih podjedinica, svaka sa EGF-om i domenima koji vežu kalcij (trombospondini). Oligomerizacija je rezultat stvaranja petolančanih upredenih zavojnica i disulfidnih veza. Čini se da vezanje za druge ECM proteine, poput kolagena, ovisi o dvovalentnim kationima. Mutacije mogu izazvati osteohondrodisplazije pseudoahondroplazije (PSACH) i multiplu epifiznu displaziju (MED).[7]
COMP je marker prometa hrskavice.[9] Jako je eksprimiran u fibroznim ožiljcima i sistemskoj sklerozi, a čini se da ima ulogu i u preuređivanju vaskularnog zida.[10]
