Protein Array containing more than 19,000 full-length human proteins using ab268118.

Z- and S- Score : The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SDs) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SDs) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target. A MAb is considered to specific to its intended target, if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.

Supplementary information

The Estrogen Inducible Protein pS2 also known as Trefoil Factor 1 (TFF1) is a small protein with a mass of about 6.6 kDa. It is mainly expressed in the mucosa of the stomach and other tissues responsive to estrogen. pS2 functions mechanically as part of the trefoil factor family known for its role in mucosal protection and repair. pS2 has a distinctive three-loop structure which is key to its interaction with other molecules and substrates in the cellular environment.
Biological function summary

This trefoil factor plays a significant role in the process of epithelial regeneration and maintaining gastrointestinal tract integrity. It is not known to be part of a complex but works through interaction with various growth factors and cytokines. Its expression is regulated by estrogen making pS2 significant in estrogen-responsive tissues. These interactions contribute to maintaining the stability of epithelial lining aiding in cellular migration and wound healing.

Pathways

PS2 influences cellular signaling involved in the gastric mucosal defense mainly interacting with the Epidermal Growth Factor (EGF) pathway. It modulates the pathway's effects on cell proliferation and migration. Its role is linked to the mitigation of tissue damage indicating a connection with other proteins like the EGF receptor contributing to the repair and defense mechanisms of epithelial tissues.

PS2 has gained attention in breast cancer research. Its expression correlates with hormone receptor-positive breast cancer making it a potential biomarker for the disease. Additionally aberrant expression levels of pS2 might relate to gastric cancer where it plays a role in tumor progression and response to therapy. pS2 is closely connected to estrogen receptor proteins which guide its involvement in these cancers influencing prognosis and treatment strategies.
