We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

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.
