Setd1a Gene Summary [Mouse]
Enables histone H3K4 methyltransferase activity. Involved in several processes, including positive regulation of gene expression; regulation of chromatin organization; and regulation of erythrocyte differentiation. Acts upstream of or within positive regulation of neural precursor cell proliferation; positive regulation of stem cell proliferation; and stem cell population maintenance. Located in euchromatin and nucleus. Is expressed in several structures, including early conceptus; integumental system; liver; nervous system; and oocyte. Used to study schizophrenia. Human ortholog(s) of this gene implicated in early-onset epilepsy 2 and neurodevelopmental disorder with speech impairment and dysmorphic facies. Orthologous to human SETD1A (SET domain containing 1A, histone lysine methyltransferase). [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 Setd1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
