Casr Gene Summary [Rat]
Enables integrin binding activity; protein kinase binding activity; and transmembrane transporter binding activity. Involved in several processes, including G protein-coupled receptor signaling pathway; blood vessel diameter maintenance; and positive regulation of cell communication. Located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and neuronal cell body. Is active in presynaptic membrane. Used to study cardiomyopathy. Biomarker of atherosclerosis; myocardial infarction; and pulmonary hypertension. Human ortholog(s) of this gene implicated in autosomal dominant hypocalcemia (multiple); hypercalcemia (multiple); hyperparathyroidism (multiple); intellectual disability; and nephrolithiasis (multiple). Orthologous to human CASR (calcium sensing receptor). [provided by Alliance of Genome Resources, Jul 2025]

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