Neurabin-2 je protein koji je kod ljudi kodiran PPP1R9B genom.^[1]^[2]

Spinofilin je regulatorni deo katalitičke jedinica proteinske fosfataze-1 (PP1). On je visoko izražen u dendritskim izbočinama, specijalizoanim delovima koji primaju veći deo ekscitatornog unosa u centralnom nervnom sistemu.^[2]
