Pepsinogens, aspartic proteinases, are classified into two groups, pepsinogen I (PGI) and pepsinogen II (PGII). PGI and PGII are mainly secreted by gastric chief cells. They are useful in diagnosing severe atrophic gastritis and stomach cancer.

Protein Induced by Vitamin K Absence or Antagonist-II (PIVKA-II), also known as Des-γ-carboxy-prothrombin (DCP), is an abnormal form of prothrombin. Normally, the prothrombin’s 10 glutamic acid residues (Glu) in the γ-carboxyglutamic acid (Gla) domain at positions 6, 7, 14, 16, 19, 20,25, 26, 29 and 32 are γ-carboxylated to Gla by vitamin-K dependent γ- glutamyl carboxylase in the liver and then secreted into plasma. In patients with hepatocellular carcinoma (HCC), γ-carboxylation of prothrombin is impaired so that PIVKA-II is formed instead of prothrombin. PIVKA-II is considered as is an efficient biomarker specific for HCC.

PCT
is a 116 amino acid (aa) protein. It is comprised of three sections of a 57 aa
N-terminal PCT, a 32 aa calcitonin and a 21 aa katacalcin. Calcitonin is a
hormone, derived from PCT cleavage. PCT is a good diagnosis marker for
bacterial infection. Other diseases such as sepsis, inflammation, surgery, heat
shock, burn injuries and cardiogenic shock can also cause an increase of PCT
level in blood.

The
progesterone is a steroid hormone which is secreted by the female reproductive
systems. Its concentration is associated with the development and regression of
the corpus luteum. The progesterone is used in evaluation of ovulation status and
assessment of the luteal phase

Progastrin-releasing peptide (ProGRP) is a stable
precursor of the gastrin releasing peptid. It is composed of GRP (residues
1–27), a cleavage site (residues 28–30), and a constant region (residues 31–98).
ProGRP is a tumor marker for the diagnosis and monitoring of small cell lung
cancer (SCLC).

Prostate specific antigen (PSA) is a serine protease produced by the prostate gland. In serum, it exists in different forms, cPSA, mainly including PSA-ACT (alpha-1-antichymotrypsin) and PSA-A2M (alpha-2-macroglobulin), fPSA (free PSA), etc. The blood level of PSA is increased in men with prostate cancer and it is considered as an indicator for prostate cancer, tumor recurrence and response to therapy.

PSA monoclonal antibodies (5B10D4, 8A9B8, 1G9G8, 4A5D10 and 1A7D4) recognize total PSA, freePSA and ACT- PSA Complex (Prostate Specific Antigen / a-1 Antichymotrypsin Complex).

Prostate-specific membrane antigen (PSMA) also known as Folate hydrolase 1 (FOLH1), Folylpoly-gamma-glutamate carboxypeptidase (FGCP), Glutamate carboxypeptidase 2 (GCP2), N-acetylated-alpha-linked acidic dipeptidase I (NAALAD1), is a type II membrane glycoprotein that is expressed in prostate tissue and to a lesser extent in the peripheral and central nervous system, small intestinal, and salivary gland tissues. PSMA has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity and has a preference for tri-alpha-glutamate peptides. The catalytic activity of PSMA involves the release of unsubstituted C-terminal glutamyl residues, typically from Ac-Asp-Glu or folylpoly-gamma-glutamates. PSMA is used as a diagnostic and prognostic indicator of prostate cancer, and as a possible marker for various neurological disorders such as schizophrenia, Alzheimer’s disease, and Huntington’s disease.

Parathyroid Hormone (PTH) is the most important endocrine regulator of calcium and phosphorus con- centration in extracellular fluid. Parathyroid Hormone (PTH) is secreted from cells of the parathyroid glands and finds Parathyroid Hormone’s major target cells in bone and kidney. Like most other protein hormones, Parathyroid Hormone (PTH) is synthesized as a preprohormone. After intracellular processing, the mature hormone is packaged within the Golgi into secretory vesicles, the secreted into blood by exocytosis. Parathyroid Hormone (PTH) is secreted as a linear protein of 84 amino acids. Recombinant Human Parathyroid Hormone (PTH) produced in E. coli is a single, non-glycosylated, polypeptide chain containing 84 amino acids.

Polypeptide hormones secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin.

PVR is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. Commonly known as Poliovirus Receptor (PVR) due to its involvement in the cellular poliovirus infection in primates. PVR’s normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells. PVR/CD155 was originally isolated based on its ability to mediate polio virus attachment to host cells. The full length (or PVR alpha isoform) is synthesized as a 417 amino acid (aa) precursor that contains a 20aa signal sequence, a 323aa extracellular region, a 24aa TM segment and a 50aa cytoplasmic tail. PVR binds other molecules including Vitronectin, Nectin-3, DNAM-1/CD226, CD96, and TIGIT but does not bind homotypically. PVR is up-regulated on endothelial cells by IFN-gamma and is highly expressed on immature thymocytes, lymph node dendritic cells, and tumor cells of epithelial and neuronal origin.
