text: Aside from the KIX domain, CBP and P300 contain many other protein binding domains that should not be confused (numbers are aa numberings):
  * CH1/TAZ1 domain, CBP[347–433], P300[323-423]
  * KIX domain, CBP[587–666], P300[566–645]
  * Bromodomain, CBP[1103–1175], P300[1067–1139]
  * CH2 domain (), CBP[1191–1317], P300[1155-1280].
  * HAT domain, CBP[1323–1700], P300[1287–1663]
  * CH3/ZZ domain, CBP[1701-1744], P300[1664-1707]
  * CH3/TAZ2 domain, CBP[1765–1846], P300[1728-1809]
  * IRF-3 binding (i-BiD), nuclear receptor coactivator binding (NCBD), or SRC1 interaction domain (SID; ), CBP[2020-2113], P300[1992-2098].
  All three CH (cysteine/histidine-rich) domains are zinc fingers.
