DDR2, ili CD167b (klaster diferencijacije 167b), je ljudski gen[1], koji je član broj 2 familije diskoidin domen receptora.
Receptor tirozin kinaze (RTK) igraju ključnu ulogu u komunikaciji ćelija sa njihovim mikro okruženjem. Ti molekuli su vezani za regulaciju ćelijskog rasta, diferencijacije i metabolizma. U više slučajeva biohemijski mehanizam kojim RTK sprovodi signal kroz membranu je pokazan da se sastoji od ligand indukovane oligomerizacije receptora, i naknadne intracelularna fosforilacije. Ova autofosforilacija dovodi do naknadne fosforilacije citosolnih proteina, kao i do asocijacije sa drugim molekulima koji su vezani za pleiotropske efekte transdukcije signala. RTK proteini imaju trojnu strukturu koja se sastoji od ekstracelularnog, transmembranskog, i citoplazmatičnog regiona. Ovaj gen kodira pripadnika nove RTK podklase sa različitim ekstracelularnim regionom koji okružuje domen sličan faktoru VIII. Alternativno spajanje (engl.splicing) ovog gena na 5' UTR dovodi do nekoliko transkript varijanti.[1]
