Anti-PAP antibody [LT3D1]

Target data

A non-specific tyrosine phosphatase that dephosphorylates a diverse number of substrates under acidic conditions (pH 4-6) including alkyl, aryl, and acyl orthophosphate monoesters and phosphorylated proteins (PubMed : 10506173, PubMed : 15280042, PubMed : 20498373, PubMed : 9584846). Has lipid phosphatase activity and inactivates lysophosphatidic acid in seminal plasma (PubMed : 10506173, PubMed : 15280042).. Isoform 2. Tyrosine phosphatase that acts as a tumor suppressor of prostate cancer through dephosphorylation of ERBB2 and deactivation of MAPK-mediated signaling (PubMed : 20498373). In addition to its tyrosine phosphatase activity has ecto-5'-nucleotidase activity in dorsal root ganglion (DRG) neurons. Generates adenosine from AMP which acts as a pain suppressor (By similarity).. PAPf39. (Microbial infection) Forms amyloid beta-sheet fibrils in semen. These fibrils, termed SEVI (semen-derived enhancer of viral infection) capture HIV virions, attach them to target cells and enhance infection (PubMed : 18083097, PubMed : 19451623, PubMed : 19897482). SEVI amyloid fibrils are degraded by polyphenol epigallocatechin-3-gallate (EGCG), a constituent of green tea (PubMed : 19451623). Target cell attachment and enhancement of HIV infection is inhibited by surfen (PubMed : 19897482). Also similarly boosts XMRV (xenotropic murine leukemia virus-related virus) infection (PubMed : 19403677).
