PubMed PubMed Product Detail Prostatic Acid Phosphatase is Belongs to the histidine acid phosphatase family.Cellular localization;Secreted and Lysosome membrane. Predominantly localized in the plasma membrane but also detected in intracellular vesicles.
Function:
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. Has lipid phosphatase activity and inactivates lysophosphatidic acid in seminal plasma.
Subunit:
Homodimer; dimer formation is required for phosphatase activity.
Subcellular Location:
Isoform 1: Secreted. Isoform 2: Cell membrane. Isoform 2: the cellular form also has ecto-5'-nucleotidase activity in dorsal root ganglion (DRG) neurons. Generates adenosine from AMP which acts as a pain suppressor. Acts as a tumor suppressor of prostate cancer through dephosphorylation of ERBB2 and deactivation of MAPK-mediated signaling.
Tissue Specificity:
Highly expressed in the prostate, restricted to glandular and ductal epithelial cells.
Post-translational modifications:
N-glycosylated. High mannose content, partially sialylated and fucosylated biantennary complex. Also fucosylated with partially sialylated triantennary complex oligosaccharides. Proteolytically cleaved in seminal fluid to produce several peptides. Peptide PAPf39, the most prominent, forms amyloid beta-sheet fibrils, SEVI (semen-derived enhancer of viral infection) which entrap HIV virions, attach them to target cells and enhance infection. SEVI amyloid fibrils are degraded by polyphenol epigallocatechin-3-gallate (EGCG), a constituent of green tea. Target cell attachment and enhancement of HIV infection is inhibited by surfen. Also similarly boosts XMRV (xenotropic murine leukemia virus-related virus) infection.
Similarity:
Belongs to the histidine acid phosphatase family.
