Answer: The function of fibroblast growth factor 3 is to inhibits growth-plate chondrocyte proliferation and limits bone elongation.
Explanation: The FGFR3 gene provides instructions for making a protein called fibroblast growth factor receptor 3. These proteins play a role in several important cellular processes, including regulation of cell growth and division (proliferation), formation of blood vessels (angiogenesis), determination of cell typewound healing, and embryo development.
This protein regulates bone growth by limiting the formation of bone from cartilage ( by a process called ossification ) it plays a important part in long bones for eg femur bone .
