Predicted to enable MHC class Ib protein binding activity; MHC class Ib receptor activity; and identical protein binding activity. Predicted to be located in early endosome membrane. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in acquired immunodeficiency syndrome; hepatitis C; human immunodeficiency virus infectious disease; malaria; and tuberculosis. Orthologous to several human genes including KIR3DL1 (killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 1); KIR3DL2 (killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 2); and KIR2DL1 (killer cell immunoglobulin like receptor, two Ig domains and long cytoplasmic tail 1).
