Vezujući protein guaninskog nukleotida G(I)/G(S)/G(T) podjedinica beta-1 je protein koji je kod ljudi kodiran GNB1 genom.^[1]

Heterotrimerni vezujući protein guaninskog nukleotida (G proteina), koji integrišu signale između receptora i efektorskih proteina, se sastoje od alfa, beta, i gama podjedinice. Te podjedinice su kodirane familijama srodnih gena. Ovaj gen kodira beta podjedinicu, koja je regulator alfa podjedinica, kao i pojedinih receptora i efektora. Ovaj gen koristi alternativne signale poliadenilacije.^[1]

Interakcije

GNB1 formira interakcije sa GNG4.^[2]^[3]
