Kl Gene Summary [Rat]
Predicted to enable fibroblast growth factor binding activity and fibroblast growth factor receptor binding activity. Involved in several processes, including norepinephrine biosynthetic process; response to angiotensin; and response to vitamin D. Predicted to be located in apical plasma membrane and extracellular region. Used to study familial hyperlipidemia; hypertension; and kidney failure. Biomarker of chronic kidney disease (multiple); hypertension; retinitis pigmentosa; secondary hyperparathyroidism; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in coronary artery disease; intracranial embolism; and spondylosis. Orthologous to human KL (klotho). [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 Kl often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
