|Other Names||G-protein-signaling modulator 1, Activator of G-protein signaling 3, GPSM1, AGS3|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Guanine nucleotide dissociation inhibitor (GDI) which functions as a receptor-independent activator of heterotrimeric G- protein signaling. Keeps G(i/o) alpha subunit in its GDP-bound form thus uncoupling heterotrimeric G-proteins signaling from G protein-coupled receptors. Controls spindle orientation and asymmetric cell fate of cerebral cortical progenitors. May also be involved in macroautophagy in intestinal cells. May play a role in drug addiction.|
|Cellular Location||Cytoplasm, cytosol. Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Golgi apparatus membrane; Peripheral membrane protein; Cytoplasmic side Cell membrane; Peripheral membrane protein; Cytoplasmic side|
|Tissue Location||Expressed in intestinal cells.|

G proteins propagate intracellular signals initiated by Gprotein-coupled receptors. GPSM1, a receptor-independent activatorof G protein signaling, is one of several factors that influencethe basal activity of G protein signaling systems (Pizzinat et al.,2001 [PubMed 11278352]).
