Id2 Gene Summary [Mouse]
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and transcription regulator inhibitor activity. Involved in several processes, including digestive tract morphogenesis; mammary gland epithelium development; and regulation of gene expression. Acts upstream of with a negative effect on regulation of gene expression; regulation of neural precursor cell proliferation; and regulation of neuron differentiation. Acts upstream of or within several processes, including hemopoiesis; nervous system development; and regulation of cell development. Located in cytoplasm; euchromatin; and nucleus. Part of protein-containing complex. Is expressed in several structures, including alimentary system; central nervous system; limb; sensory organ; and urinary system. Orthologous to human ID2 (inhibitor of DNA binding 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 Id2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
