Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins. Able to activate GNAI1, GNAO1 and GNAQ, but not GNAS by exchanging bound GDP for free GTP. Involved in regulation of microtubule pulling forces during mitotic movement of chromosomes by stimulating G(i)-alpha protein, possibly leading to release G(i)-alpha-GTP and NuMA proteins from the NuMA-GPSM2-G(i)-alpha-GDP complex. Also acts as an activator for G(q)-alpha (GNAQ) protein by enhancing the G(q)-coupled receptor-mediated ERK activation.

Human NCS-1 and Ric8a reproduce the binding and maintain the structural requirements at these key positions. Drosophila Ric8a and Galphas regulate synapse number and neurotransmitter release, and both are functionally linked to Frq2. PMID: 25074811
Results confirmed that Ric-8A can directly bind to AGS3S but failed to facilitate Galpha(i)-induced suppression of adenylyl cyclase, suggesting that it may not serve as a guanine exchange factor for AGS3/Galpha(i/o)-GDP complex in a cellular environment. PMID: 25480567
Ric-8A co-localized with Vps34 at the midbody. PMID: 24466196
The ubiquitination of Galphai2 and Galphaq is suppressed by expression of Ric-8A. The suppression likely requires Ric-8A interaction with these Galpha proteins; the C-terminal truncation of Galphaq and Galphai2 completely abrogates their interaction with Ric-8A. PMID: 23665327
