Progress of research on the mechanism of GPSM2 in tumor development

G-protein signaling modulator 2 (GPSM2) is a negative regulator of G protein coupled receptor signaling pathway, which plays an important role in cell growth. In recent years, it has been found that GPSM2 is abnormally expressed in a variety of malignant tumors and is related to many clinical symptoms of tumors. Based on the structure and function of GPSM2, this paper discusses its role and mechanism in tumor development, so as to identify new targets for tumor diagnosis and treatment.
