Intracellular
Cell type enhanced (Suprabasal keratinocytes, Proximal tubular cells, Squamous epithelial cells, Basal squamous epithelial cells)
Low immune cell specificity
Cell line enhanced (HDLM-2, HMC-1, NB-4, RPMI-8226)
Interacts with GNAO1, GNAI2 and GNAI3 (By similarity). Interacts with GNAI1 (PubMed:18434541, PubMed:21115486). Interacts (via RGS and GoLoco domains) with GNAI1; the interaction occurs in the centrosomes. Interaction with GNAI1 or GNAI3 (via active GTP- or inactive GDP-bound forms) prevents association of RGS14 with centrosomes or nuclear localization (By similarity). Interacts with RABGEF1; the interactions is GTP-dependent. Interacts with RAP2A; the interactions is GTP-dependent and does not alter its function on G(i) alpha subunits either as GAP or as GDI (By similarity). Associates with microtubules (PubMed:15917656). Found in a complex with at least BRAF, HRAS, MAP2K1, MAPK3 and RGS14. Interacts with RIC8A (via C-terminus). Interacts (via RBD 1 domain) with HRAS (active GTP-bound form preferentially). Interacts (via RBD domains) with BRAF (via N-terminus); the interaction mediates the formation of a ternary complex with RAF1. Interacts (via RBD domains) with RAF1 (via N-terminus); the interaction mediates the formation of a ternary complex with BRAF. Interacts with KRAS (active GTP-bound form preferentially), MRAS (active GTP-bound form preferentially), NRAS (active GTP-bound form preferentially) and RRAS (active GTP-bound form preferentially).
