First immunoglobulin (Ig) domain of rat MRC OX-2 antigen (also known as CD200) and similar domains
Ig1_ MRC-OX-2_like: domain similar to the first immunoglobulin (Ig) domain of rat MRC OX-2 antigen (also known as CD200). MRC OX-2 is a membrane glycoprotein expressed in a variety of lymphoid and non-lymphoid cells in rats. It has a similar broad distribution pattern in humans. MRC OX-2 may regulate myeloid cell activity. The protein has an extracellular portion containing two Ig-like domains, a transmembrane portion, and a cytoplasmic portion.
