IGF-II (Insulin-like Growth Factor-II) is a polypeptide growth factor that stimulates the proliferation of a wide range of cell types. IGF-II is similar to insulin by structure and function, but has a higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, and signals through the tyrosine kinase type I receptor IGF-1R as well as the IGF-II/Mannose-6-phosphate receptor.
