Kmt5b Gene Summary [Rat]
Predicted to enable S-adenosyl-L-methionine binding activity; chromatin binding activity; and histone H4K20 methyltransferase activity. Predicted to be involved in DNA repair; positive regulation of double-strand break repair via nonhomologous end joining; and positive regulation of isotype switching. Predicted to be located in several cellular components, including condensed chromosome, centromeric region; microtubule cytoskeleton; and nuclear lumen. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 51. Orthologous to human KMT5B (lysine methyltransferase 5B).

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 rat Kmt5b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
