Anti-Sulfotyrosine Antibody, Clone Sulfo-1C-A2

Sulfotyrosine is a common post-translational modification of secretory, plasma membrane, and lysosomal proteins. The sulfation reaction is catalyzed by specific sulfotransferase enzymes in the trans-Golgi-network. Tyrosine sulfation occurs in all multicellular organisms and up to 1% of the tyrosines in the total protein content of a cell can be sulfated. Sulfotyrosines mediates many receptor-ligand binding interactions, including the interaction of P-selectin glycoprotein ligand-1 with P-selectin, factor VIII binding to von Willebrand factor, and interactions between thrombin and hirudin. Sulfotyrosine is also involved in the entry of several parasites and viruses; for example, tyrosine sulfation of the HIV-1 co-receptor CCR5 is required for viral entry into host cells, and tyrosine sulfation of the Duffy antigen/receptor for chemokines is crucial for erythrocyte invasion by the malaria parasite Plasmodium vivax.
This clone was derived from the antibody described in Kehoe et al., 2006.

Recognizes sulfated tyrosine residues on various proteins. Does not recognize phosphotyrosine or unmodified tyrosines.

The antibody is predicted to recognize any sulfotyrosine, regardless of surrounding amino acid sequence.

Epitope: Sulfated Tyrosine

This antibody was developed using a phage display library as described in Kehoe et al., 2006. The selection antigens were KAKISDP-DY(SO3)MTGYMDAC and KDKKYATEY(SO3)-EYLDYDFC
