Med1 Gene Summary [Mouse]
Enables several functions, including nuclear receptor binding activity; promoter-specific chromatin binding activity; and transcription coregulator activity. Involved in several processes, including camera-type eye development; circulatory system development; and myeloid cell development. Acts upstream of or within several processes, including hemopoiesis; mammary gland development; and regulation of signal transduction. Located in nucleus. Part of mediator complex. Is expressed in several structures, including central nervous system; genitourinary system; gut; hemolymphoid system gland; and lung. Used to study congestive heart failure and dilated cardiomyopathy. Orthologous to human MED1 (mediator complex subunit 1). [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 Med1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
