Hmgb2 Gene Summary [Mouse]
Enables DNA-binding transcription factor binding activity; cis-regulatory region sequence-specific DNA binding activity; and protein domain specific binding activity. Involved in several processes, including regulation of gene expression; regulation of stem cell proliferation; and response to lipopolysaccharide. Acts upstream of or within several processes, including male gonad development; negative regulation of extrinsic apoptotic signaling pathway via death domain receptors; and spermatid nucleus differentiation. Located in several cellular components, including chromatin; extracellular space; and nucleus. Is expressed in several structures, including alimentary system; brain; branchial arch; retina; and urinary system. Orthologous to human HMGB2 (high mobility group box 2).

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 Hmgb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
