Overview of FGF Family

The Fibroblast Growth Factor (FGF) family is a group of signaling proteins that play crucial roles in various biological processes, including cell growth, development, and wound healing. There are 22 members in the FGF family, which can be further divided into canonical and non-canonical subfamilies based on their structure and function. Canonical FGFs bind to specific cell surface receptors called Fibroblast Growth Factor Receptors (FGFRs), which then activate intracellular signaling pathways that regulate cell proliferation, differentiation, and survival.

Non-canonical FGFs, on the other hand, do not bind to FGFRs and instead interact with other cell surface receptors or extracellular matrix components to mediate their effects. The FGF family members are highly conserved across species, indicating their importance in evolution and development. Dysregulation of FGF signaling has been implicated in various diseases, including cancer, skeletal disorders, and developmental abnormalities. Therefore, understanding the functions and mechanisms of action of FGF family members is essential for developing targeted therapies for these conditions. Research on the FGF family continues to uncover new roles and interactions of these proteins, expanding our knowledge of their functions in health and disease.
