Function. May be a cytokine receptor for GPR15LG. May be a tumor suppressor; together with GPR15LG has a growth inhibitory effect on colon cancer cells which includes G1 cell cycle arrest. May play a role in breast tumorigenesis.

Subunit / interactions. Interacts with LGALS1; leads to an increased amount of LGALS1 on the cell surface. Interacts with GPR15LG; the interaction is direct.

Subcellular location. Cell membrane.

Tissue specificity. Highly expressed in breast cancer, but shows a restricted expression pattern in normal tissues such as adipose, adrenal gland, kidney, lung, mammary gland, placenta, thyroid, trachea, and uterus. Also expressed in colon; down-regulated in colon cancer tissues.
