Function

Acid phosphatase (ACP, EC number 3.1.3.2) is an enzyme which removes phosphate from other molecules during digestion. It catalyzes the conversion of orthophosphoric monoester and H₂O to alcohol and phosphoric acid. The enzyme is most effective in acidic environment, hence its name.^[1]

Prostatic ACP (PSAP) is produced by the prostate.
Purple ACP (PAP) or tartrate-resistant ACP contains a dinuclear Fe center and their oxidized form in solution maintains a purple color.
Histidine ACP (HAP) catalyzes the transfer of phosphoryl group using an active-site histidine.
BA42

BA42 belongs to the TPM protein family from Pfam. The TPM domain family is named after the three founding proteins TLP18.3, Psb32 and MOLO-1. TPM domains have a characteristic fold (αβαβαββαα or βαβαββαα) composed of α helices (3+3^[2] or 2+3^[3]) flanking four central β strands. The TPM fold has not been found in other protein domains to date. TPM was previously referred to as "DUF477" and "Repair_PSII".

In plants, the TPM domain-containing proteins TLP18.3 and Psb32 that have been implicated in the photosystem II (PSII) repair cycle. It may be involved in the regulation of synthesis/degradation of the D1 protein of the PSII core and in the assembly of PSII monomers into dimers in the grana stacks.^[4]

In the model nematode C. elegans, the MOLO-1 protein is an auxiliary subunit that positively modulates the gating of levamisole-sensitive acetylcholine receptors.^[5]

Disease

PSAP is found in increased amounts in patients who have prostate cancer.

Relevance

PSAP was used as a prostate cancer marker before the develpement of prostate specific antigen (PSA) as one.
