Tacr1 Gene Summary [Rat]
Enables substance P receptor activity. Involved in several processes, including learning or memory; positive regulation of cell communication; and regulation of cell migration. Located in cell body; cell surface; and dendrite. Is active in postsynaptic membrane. Used to study central sleep apnea; cystitis; pancreatitis; and pulmonary hypertension. Biomarker of acute necrotizing pancreatitis; allergic rhinitis; asthma; colitis; and respiratory syncytial virus infectious disease. Human ortholog(s) of this gene implicated in developmental disorder of mental health and exercise-induced bronchoconstriction. Orthologous to human TACR1 (tachykinin receptor 1).

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 Tacr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
