Insulin-like growth factor (IGF) is a peptide hormone (ligand) that binds and activates IGF receptor tyrosine kinase. Once the ligands bind the receptors, the cell undergoes cell division and multiply. Therefore, IGF is important for the growth of muscle and bone tissues during puberty. The way the IGF hormone works is that the hormone-bound IGF receptor tyrosine kinase increases the levels of cyclins inside of the cell and promotes the progression of the cell cycle. Describe how receptor tyrosine kinase works in a general sense and how cyclins regulate the cell cycle.
