Ighmbp2 Gene Summary [Rat]
Enables DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in several cellular components, including growth cone; neuronal cell body; and nuclear body. Predicted to be part of ribonucleoprotein complex. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease axonal type 2S and autosomal recessive distal hereditary motor neuronopathy 1. Orthologous to human IGHMBP2 (immunoglobulin mu DNA binding protein 2). [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 Ighmbp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
