Trim28 Gene Summary [Mouse]
Enables DNA binding activity; protein kinase activity; and transcription coactivator activity. Involved in DNA methylation-dependent constitutive heterochromatin formation; epithelial to mesenchymal transition; and positive regulation of DNA-templated transcription. Acts upstream of or within several processes, including convergent extension involved in axis elongation; embryo implantation; and negative regulation of RNA biosynthetic process. Located in euchromatin; heterochromatin; and nucleoplasm. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including branchial arch; central nervous system; early conceptus; genitourinary system; and limb primordium. Orthologous to human TRIM28 (tripartite motif containing 28). [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 Trim28 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
