Summary of "Monoclonal Antibody Targeting a Conserved N-Terminal Epitope on 2A of Enteroviruses."

Several members of enteroviruses (EVs) that belong to the EVs A and B species cause hand, foot, and mouth disease (HFMD) in infants and young children. The virus-specific protease 2A is conserved in all the EV species, thus developing a monoclonal antibody (mAb) against 2A may facilitate the identification from the HFMD-associated pathogens. In this study, we achieved a murine mAb, named 5A3, specifically toward EVA71 2A by using the traditional hybridoma technique. The mAb 5A3 recognizes 2A of both EVs A and B species, which was demonstrated by indirect fluorescent assay and Western blotting. Furthermore, a conserved N-terminal epitope on 2A recognized by mAb 5A3 was defined by using an overlapping peptide-based enzyme-linked immunosorbent assay (ELISA). Therefore, the unique mAb targeting conserved EVs 2A can be used as an important tool during both identifying the causative agent of HFMD and elucidating the pathological mechanism of HFMD.

Medical and Biotech [MESH] Definitions

Methods used for studying the interactions of antibodies with specific regions of protein antigens. Important applications of epitope mapping are found within the area of immunochemistry.

An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.

An approximately 250 amino acid domain common to AAA ATPases and AAA Proteins. It consists of a highly conserved N-terminal P-Loop ATPase subdomain with an alpha-beta-alpha conformation, and a less-conserved C-terminal subdomain with an all alpha conformation. The N-terminal subdomain includes Walker A and Walker B motifs which function in ATP binding and hydrolysis.

Highly conserved protein domains of approximately 130 to 140 amino acids. The SET domain was first identified in the Drosophila proteins (S)u(var)3-9, (E)nhancer-of-zeste and (T)rithorax and occurs in other proteins with a variety of functions, including histone-lysine N-methyltransferases. Structurally, it consists of BETA-SHEETS interspersed among loops and turns that result in an "L" shape. The most conserved motifs are a stretch at the C-terminal that contains a strictly conserved tyrosine residue and an adjacent loop that the C-terminal segment passes through to form a "knot". These motifs and especially the tyrosine residue are essential for S-ADENOSYLMETHIONINE binding and catalysis. The PR domain has high homology to the catalytic region of the SET domain and occurs at the N-terminal of PRDM proteins such as PRDM1 PROTEIN.

An anti-CD52 ANTIGEN monoclonal antibody used for the treatment of certain types of CD52-positive lymphomas (e.g., CHRONIC LYMPHOCYTIC LEUKEMIA; CUTANEOUS T-CELL LYMPHOMA; and T-CELL LYMPHOMA). Its mode of actions include ANTIBODY-DEPENDENT CELL CYTOTOXICITY.
