proPSA

Aliases:
This biomarker is also known as:
  • free prostate-specific antigen (PSA) isoform
  • [-2]proPSA
  • proPSA

Description…

ProPSA (-2), or [-2]proPSA, is a PSA isoform which has a leader peptide (-2) amino acids at its N terminal region and does not interact with ACT or alpha-2-macroglobulin or spermidine and therefore is detected as a separate isoform. ProPSA is produced primarily in the peripheral zone of the prostate gland and therefore is very useful in distinguishing between prostate cancer patients with PSA range of 2-10, from those who have BPH. Percent proPSA is the ratio of proPSA to free PSA. In July 2012 the FDA approved an assay measuring levels of [-2]proPSA for monitoring and diagnostic purposes.
