| Protein existence | Evidence at protein level |
General annotation (Comments)
| 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. Ref.6 Ref.7 |
| Subunit structure | Interacts with GNAI1, GNAI2 and GNAI3 preferentially in their GDP-bound state. May also interact with GNAO1. Interacts with STK11/LKB1 and MACF1 By similarity. Interacts with INSC/inscuteable and FRMPD1. Ref.8 Ref.9 |
| Subcellular 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 Ref.7 Ref.9. |
| Tissue specificity | Expressed in intestinal cells. Ref.7 |
| Domain | The GoLoco domains mediate interaction with G(i/o) alpha By similarity. The GoLoco domains are essential for the GDI activity toward G(i/o) alpha. |
| Post-translational modification | Phosphorylation regulates interaction with G(i/o) alpha By similarity. |
| Sequence similarities | Belongs to the GPSM family. Contains 4 GoLoco domains. Contains 9 TPR repeats. |
| Sequence caution | The sequence AAH09979.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAH17353.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAB55951.1 differs from that shown. Reason: Frameshift at position 657. The sequence CAI19339.1 differs from that shown. Reason: Erroneous gene model prediction. |
