The Somatotropin family is a protein family whose titular representative is somatotropin, also known as growth hormone, a hormone that plays an important role in growth control.
[1] Other members include choriomammotropin (lactogen), its placental analogue;[2] prolactin, which promotes lactation in the mammary gland, and placental prolactin-related proteins;[3] proliferin and proliferin related protein;[4] and somatolactin from various fishes.
[5][6] The 3D structure of bovine somatotropin has been predicted using a combination of heuristics and energy minimisation.
