protein gene tissue distribution preferred ligand function CCKA (CCK1) CCKAR primarily gastrointestinal tract, lesser amounts in the CNS sulfated CCK >> nonsulfated CCK ≈ nonsulfated CCK stimulation of bicarb secretion, gall bladder emptying and inhibiting gut motility CCKB (CCK2) CCKBR primarily CNS, lesser amounts in the gastrointestinal tract gastrin ≈ CCK (receptor does not descriminate between sulfated and nonsulfated peptides) regulation of nociception, anxiety, memory and hunger References
