Tsix Gene Summary [Mouse]
Acts upstream of or within inactivation of paternal X chromosome by genomic imprinting; negative regulation of transcription by RNA polymerase II; and transcription initiation-coupled chromatin remodeling. Is expressed in several structures, including early conceptus; liver; and retina nuclear layer. Orthologous to human TSIX (TSIX transcript, XIST antisense RNA).

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