| Gene Summary | GPR155, which resides on chromosome 2q31.1, comprises eighteen exons and encodes a 97 kDa protein. GPR155 is a member of the seven-transmembrane domain of the GPCR family. Ligand binding activates the guanine nucleotide exchange factor activity of GPCRs that exchange GDP for GTP on its associated G protein. The Gα subunit bound to GTP dissociates from the Gβ and Gγ subunits to activate intracellular signaling proteins or target proteins directly. Limited information is available on the ligands for GPCRs at present. Huang XP, et al. detected some ligands for other GPCR families, GPR68 and GPR6514. GPCRs mediate diverse physiological processes such as the visual sensing, immune function, cell proliferation, and tumor metastasis15,16. It is therefore not surprising GPCRs represent 30–50% of the targets of currently marketed therapeutic drugs17,18,19,20. GPR155 is a unique member of GPCRs and there have been only a few reports on involvement in malignancies, such as follicular type papillary thyroid carcinoma and colorectal cancer21,22. In those earlier studies, GPR155 was listed in the results of microarray or proteomic analysis, and no data on the function and clinical significance of GPR155 was presented. GPR155 may be a biomarker that is useful for the diagnosis and prediction of hematogenous metastasis of patients with GC. |
