This domain is found at the C-terminal end of bovine Osteocalcin (BGLAP) and similar short sequences mainly found in animals. The carboxylated form of BGLAP is one of the main organic components of the bone matrix. The uncarboxylated form acts as a hormone secreted by osteoblasts, which regulates different cellular processes, such as energy metabolism, male fertility and brain development. This domain is predicted to show an all alpha-configuration.	Domain
