Tpst2 Gene Summary [Mouse]
Enables protein-tyrosine sulfotransferase activity. Involved in peptidyl-tyrosine sulfation. Acts upstream of or within fusion of sperm to egg plasma membrane involved in single fertilization and prevention of polyspermy. Is active in Golgi lumen and trans-Golgi network. Orthologous to human TPST2 (tyrosylprotein sulfotransferase 2). [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 Tpst2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
