Setdb1

Enables DNA binding activity; histone H3K9 methyltransferase activity; and promoter-specific chromatin binding activity. Involved in DNA methylation-dependent constitutive heterochromatin formation; negative regulation of single stranded viral RNA replication via double stranded DNA intermediate; and transposable element silencing by heterochromatin formation. Acts upstream of or within bone development; inner cell mass cell proliferation; and negative regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including 1-cell stage embryo; central nervous system; heart; long bone; and oocyte. Human ortholog(s) of this gene implicated in autistic disorder and lung cancer. Orthologous to human SETDB1 (SET domain bifurcated histone lysine methyltransferase 1).

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 Setdb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
