CD200R1
Ćelijskopovršinski transmembranski glikoproteinski CD200 receptor 1 jest protein koji je kod ljudi kodiran genom CD200R1 sa hromosoma 3.[5][6][7] CD200R1 se eksprimira na površini mijeloidnih ćelija [8] i CD4+ T-ćelija.[9] Interragira sa CD200 transmembranskim glikoproteinom koji se može eksprimirati na različitim ćelijama uključujući neurone,[10] epithelial cells,[11] endotelne ćelije,[12] fibroblaste,[13] i limfoidne ćelije.[14]
Aktivacija CD200R1 regulira ekspresiju proupalnih molekula kao što je faktor tumorske nekroze (TNF-alfa),[15] interferoni i inducibilnadušik-oksidna sintetaza (iNOS).[16]

Funkcija
urediOvaj gen kodira receptor za OX-2 membranski glikoprotein. I receptor i supstrat su glikoproteini ćelijske površine koji sadrže dva imunoglobulinska domena. Ovaj receptor je ograničen na površine loze mijeloidnih ćelija i interakcija receptor-supstrat može funkcionirati kao mijeloidni regulatorni signal. Studije srodnog gena na miševima sugeriraju da ova interakcija može kontrolirati mijeloidnu funkciju na tkivno specifičan način. Alternativna prerada ovog gena rezultira višestrukim varijantama transkripta.[7]
