Med4 Gene Summary [Mouse]
Predicted to enable nuclear thyroid hormone receptor binding activity and transcription coactivator activity. Predicted to be involved in positive regulation of transcription initiation by RNA polymerase II and transcription by RNA polymerase II. Part of mediator complex. Is expressed in 1st branchial arch; genitourinary system; limb; and trunk somite. Orthologous to human MED4 (mediator complex subunit 4). [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 Med4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
