P300-CBP koaktivatorska familija

E1A vezujući protein p300
Kristalografska struktura histonskog acetiltransferaznog domena EP300 (N-terminus = plavo, C-terminus = crveno) u kompleksu sa inhibitorom lizin-KoA (ugljenik = belo, kiseonik = crveno, azot = plavo, fosfor = naranđasto).[1]

p300-CBP koaktivatorska familija se sastoji od dva blisko srodna transkripciona koaktivirajuća proteina (ili koaktivatora):

1. p300 (EP300 ili E1A vezujući protein p300)
2. CBP (CREB-vezujući protein ili CREBBP)

Proteini p300 i CBP formiraju interakcije sa brojnim transkripcionim faktorima i deluju tako što povišavaju izražavanje njihovih ciljnih gena.^[2][3]
