Tnp1 Gene Summary [Rat]
Predicted to enable DNA binding activity. Predicted to be involved in several processes, including nucleosome disassembly; regulation of gene expression; and spermatid nucleus differentiation. Predicted to act upstream of or within spermatogenesis. Located in male germ cell nucleus. Orthologous to human TNP1 (transition protein 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 rat Tnp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
