Macroh2a2 Gene Summary [Rat]
Predicted to enable RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and chromatin DNA binding activity. Predicted to be a structural constituent of chromatin. Predicted to be involved in several processes, including establishment of protein localization to chromatin; negative regulation of macromolecule biosynthetic process; and positive regulation of keratinocyte differentiation. Predicted to act upstream of or within sex-chromosome dosage compensation. Located in chromatin. Orthologous to human MACROH2A2 (macroH2A.2 histone).

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 Macroh2a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
