Follistatin-related protein 3 (FSTL3) is a secreted glycoprotein involved in a myriad of intracellular signaling pathways by binding to activin-A and myostatin, members of the TGF-ß family, thereby suppressing their cellular activity. Thus, FSTL3 plays a role in health and disease. Analysis of FSTL3 expression can serve as diagnostic biomarker and in-depth knowledge of its actions on intracellular signaling pathways will lead to the development of new therapeutic approaches.

Background Information

Human follistatin-related protein 3 (FSTL3) is a secrected glycoprotein, which is structurally and functionally related to the activin-binding protein follistatin. It is expressed in various organs and tissues such as placenta, testis, heart and lung and plays an important role in a variety of cellular functions. By binding to activin-A and myostatin, both members of the TGF-ß family, FSTL3 antagonizes their cellular activity, thereby regulating physiological processes including cell differentiation and proliferation, metabolic pathways, inflammation and tumor development.
