Guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades. The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state. Signaling by an activated GPCR promotes GDP release and GTP binding. The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal. Both GDP release and GTP hydrolysis are modulated by numerous regulatory proteins (PubMed:8774883, PubMed:18434541). Signaling is mediated via effector proteins, such as adenylate cyclase. Inhibits adenylate cyclase activity, leading to decreased intracellular cAMP levels (By similarity). The inactive GDP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. Required for normal cytokinesis during mitosis (PubMed:17635935). Required for cortical dynein-dynactin complex recruitment during metaphase (PubMed:22327364).By similarity4 Publications

Heterotrimeric G proteins are composed of 3 units; alpha, beta and gamma. Part of a spindle orientation complex at least composed of GNAI1, GPSM2 and NUMA1 (PubMed:26766442). The alpha chain contains the guanine nucleotide binding site. Identified in complex with the beta subunit GNB1 and the gamma subunit GNG1 (PubMed:22383884). Identified in complex with the beta subunit GNB1 and the gamma subunit GNG2 (PubMed:18434541). GTP binding causes dissociation of the heterotrimer, liberating the individual subunits so that they can interact with downstream effector proteins (PubMed:22383884). Interacts (GDP-bound form) with GPSM1; this inhibits guanine nucleotide exchange and GTP binding (By similarity). Interacts (GDP-bound form) with GPSM2 (via GoLoco domains); this inhibits guanine nucleotide exchange (PubMed:22952234). Interacts with RGS10; this strongly enhances GTP hydrolysis (PubMed:8774883, PubMed:18434541). Interacts with RGS1 and RGS16; this strongly enhances GTPase activity (PubMed:18434541). Interacts with RGS4 (PubMed:18434541). Interacts with RGS12 (PubMed:18434541). Interacts (via active GTP- or inactive GDP-bound forms) with RGS14 (via RGS and GoLoco domains) (PubMed:11976690, PubMed:18434541, PubMed:21115486, PubMed:22383884). Interacts with RGS3, RGS6, RGS7, RGS8, RGS17, RGS18 and RGS20 (in vitro) (PubMed:18434541). Interacts (GDP-bound form) with RIC8A (via C-terminus) (By similarity).By similarity9 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i9F88311B46E62DE3
