TPST2 (Tyrosylprotein Sulfotransferase 2) is an enzyme that catalyzes the sulfation of tyrosine residues in secreted and transmembrane proteins, a post-translational modification critical for protein-protein interactions, receptor signaling, and cellular adhesion. It is part of the sulfotransferase family, localized in the Golgi apparatus, and works in tandem with TPST1. though their substrate specificities differ. TPST2-mediated sulfation modulates the activity of various physiologically important proteins, including chemokines (e.g., CCL2. CXCR4), coagulation factors, and adhesion molecules (e.g., PSGL-1), influencing immune responses, hemostasis, and inflammation.
Antibodies targeting TPST2 are essential tools for studying its expression, localization, and functional roles in biological systems. They are widely used in techniques like Western blotting, immunohistochemistry, and immunofluorescence to investigate TPST2 regulation in diseases such as cancer, autoimmune disorders, and cardiovascular conditions. For example, altered TPST2 expression has been linked to tumor progression due to its role in modifying chemokine receptors involved in metastasis. TPST2 antibodies also aid in exploring genetic deficiencies linked to rare disorders, such as idiopathic hypogonadotropic hypogonadism, where TPST2 mutations impair G-protein-coupled receptor sulfation. These antibodies enable researchers to dissect TPST2's contribution to cellular pathways and its potential as a therapeutic target.
