NCIt definition : Prostatic acid phosphatase (386 aa, 45 kDa) is encoded by the human ACP3 gene. This
protein is involved in the dephosphorylation of both lipids and tyrosine and has ecto-5'-nucleotidase
activity.;
Alternative definition : NCI-GLOSS: An enzyme produced by the prostate. It may be found in increased amounts
in men who have prostate cancer.;
NCIt note : Prostatic acid phosphatase precursor catalyzes the conversion of orthophosphoric monoester
to alcohol and orthophosphate. ACPP is synthesized under androgen regulation and secreted
by the epithelial cells of the prostrate gland. (EntrezGene); Prostatic acid phosphatase is proteolytically cleaved in seminal fluid, which produces
several peptides. One peptide, PAPf39 a 39 amino acid peptide comprised of residues
248-286, forms fibrils resembling amyloid beta-sheets. This peptide is also known
as SEVI (semen-derived enhancer of viral infection) because the fibrils bind to HIV
(and possibly other) virions and promote viral attachment to and infection of target
cells. (UniProt);
