Funkcija

uredi

ADAMTS5 je član porodice proteina ADAMTS (dezintegrin i metaloproteinaza sa motivima trombospondina). Članovi porodice dijele nekoliko različitih proteinskih modula, uključujući propeptidnu regiju, metaloproteinazni domen, disintegrinski domen i trombospondinski tip 1 (TS) motiva. Pojedini članovi ove porodice razlikuju se po broju C-terminalnih TS motiva, a neki imaju jedinstvene ove motive. Enzim kodiran ovim genom sadrži dva C-terminalna TS motiva i funkcionira kao agrekanaza za cijepanje agrekana, glavnog hrskavičnog proteoglikana.[7] ADAMTS5 također može imati ulogu u patogenezi ljudskog osteoartritisa.[8]

Studije na životinjama

uredi

Genetički modificirani miševi kod kojih je deletirana katalitsk domen ADAMTS5 otporni su na destrukciju hrskavice u eksperimentalnom modelu osteoartritisa.[9] ADAMTS5 je glavna agrekanaza u mišjoj hrskavici u mišjem modelu upalnog artritisa.[10]
