PRESENCE OF PTH-LIKE AND PTH-RELATED PEPTIDELIKE MOLECULES IN SUBMAMMALIAN VERTEBRATES

摘要

The endocrine Stannius corpuscles (CS) of holostean and teleostean fishes produce molecules resembling mammalian parathyroid hormone (PTH). We have shown thar extracts of eel CS contain proteins related to these PTH-related peptides (PTHrp) and, furthermore, that reptiles, amphibians, fish and Agnatha have DNA fragments homologous to the chicken PTHrp gene.
