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]

Interakcije

PPP1R9B formira interakcije sa PPP1CB,^[3] PPP1CA,^[3] Dopamine receptor D2,^[4] P16,^[5] PPP1CC,^[3]^[4] TIAM1^[6] i PPP1R2.^[7]
