Ighmbp2 Gene Summary [Mouse]
Enables several functions, including ATP hydrolysis activity; G-rich single-stranded DNA binding activity; and ribosome binding activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II; neuromuscular process; and spinal cord motor neuron differentiation. Located in several cellular components, including growth cone; neuronal cell body; and perinuclear region of cytoplasm. Part of ribonucleoprotein complex. Is expressed in several structures, including genitourinary system; heart; liver; lung; and nervous system. Used to study Charcot-Marie-Tooth disease axonal type 2S and autosomal recessive distal hereditary motor neuronopathy 1. 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 mouse 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.
