Mbd1 Gene Summary [Mouse]
Enables DNA binding activity. Predicted to be involved in DNA methylation-dependent constitutive heterochromatin formation; negative regulation of astrocyte differentiation; and negative regulation of transcription by RNA polymerase II. Located in cytoplasm; heterochromatin; and nuclear lumen. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; and retina. Human ortholog(s) of this gene implicated in lung cancer. Orthologous to human MBD1 (methyl-CpG binding domain protein 1). [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 Mbd1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
