Igf2r Gene Summary [Rat]
Enables several functions, including G-protein alpha-subunit binding activity; insulin-like growth factor II binding activity; and retinoic acid binding activity. Involved in several processes, including animal organ regeneration; response to retinoic acid; and response to tetrachloromethane. Located in several cellular components, including late endosome; perinuclear region of cytoplasm; and trans-Golgi network. Part of clathrin coat. Used to study lung adenocarcinoma. Biomarker of amyotrophic lateral sclerosis. Human ortholog(s) of this gene implicated in diabetes mellitus (multiple); hepatocellular carcinoma; in situ carcinoma (multiple); and nephroblastoma. Orthologous to human IGF2R (insulin like growth factor 2 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 Igf2r often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
