Cckbr Gene Summary [Rat]
Cholecystokinin was one of the first gastrointestinal peptides discovered in the mammalian brain. Cholecystokinin receptors are members of the G protein-coupled receptor superfamily, stimulating phosphatidylinositol turnover and intracellular calcium mobilization. This gene encodes a cholecystokinin receptor of the B subtype. These receptors occur throughout the central nervous system where they modulate anxiety, analgesia, arousal, and neuroleptic activity.

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cckbr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
