Product details:
Human GST3 / GST pi ELISA Kit (ab277423) is an
in-vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human GST3 / GST pi in serum (human GST3 / GST pi concentration is low in normal serum/plasma, and may not be detectable in this assay), plasma and cell culture supernatants.
This assay employs an antibody specific for Human GST3 / GST pi coated on a 96-well plate. Standards and samples are pipetted into the wells and Human GST3 / GST pi present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and biotinylated anti-Human GST3 / GST pi antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Human GST3 / GST pi bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

GST3 also known as GST pi or GSTP is a protein part of the glutathione S-transferase family. These enzymes are involved in detoxifying processes by catalyzing the conjugation of glutathione to harmful substances. GSTP is approximately 23 kDa in size and is predominantly expressed in mammalian tissues including the liver and lung. These tissues play active roles in detoxifying external chemicals and managing oxidative stress in the body.
Biological function summary
GST3 contributes to the detoxification of xenobiotics and electrophilic compounds playing a protective role against cellular damage. It can exist as homo-dimers or form hetero-dimers with other GST family members participating in larger enzyme complexes. Through conjugation reactions GSTP helps in the detoxification processes thereby aiding cellular defenses and maintaining cellular redox balance.
Pathways
GST3 is an integral part of the phase II detoxification pathway and oxidative stress response. It interacts closely with other proteins such as Nrf2 (Nuclear factor erythroid 2-related factor 2) and helps regulate the transcription of antioxidant proteins that protect against oxidative damage. This enzyme plays a role in modulating the MAPK signaling pathway which influences cell proliferation and apoptosis.
GSTP has links to several cancer types including liver and lung cancer. Its overexpression in tumors suggests its role in cancer cell survival and resistance to chemotherapy. GSTP interacts with cancer-associated proteins like c-Jun N-terminal kinase (JNK) influencing pathways that lead to aberrant cellular growth and transformation. It also has associations with neurodegenerative diseases given its role in counteracting oxidative stress which commonly underpins neurodegeneration.
