Vdr Gene Summary [Rat]
Enables calcitriol binding activity; nuclear receptor activity; and sequence-specific DNA binding activity. Involved in several processes, including cellular response to amyloid-beta; negative regulation of bone trabecula formation; and positive regulation of parathyroid hormone secretion. Located in several cellular components, including T-tubule; chromatin; and nuclear lumen. Used to study vitamin D-dependent rickets type 2A. Biomarker of retinal degeneration and secondary hyperparathyroidism. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); carcinoma (multiple); liver disease (multiple); lung disease (multiple); and melanoma (multiple). Orthologous to human VDR (vitamin D 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 Vdr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
