G-protein-signaling modulator 2, also called LGN for its 10 Leucine-Glycine-Asparagine repeats, is a protein that in humans is encoded by the GPSM2 gene.^[5][6][7]

Function

Heterotrimeric G proteins transduce extracellular signals received by cell surface receptors into integrated cellular responses. GPSM2 belongs to a group of proteins that modulate activation of G proteins (Blumer et al., 2002).[supplied by OMIM]^[7]

Interactions

GPSM2 has been shown to interact with nuclear mitotic apparatus protein 1^[8] and GNAI2.^[6][9]
