The biological properties of bovine parathyroid hormone (1-41), a fragment generated from the native hormone by human leukocytes.

Abstract:

:Native bovine parathyroid hormone (bPTH) was found to be readily cleaved with human leukocyte elastase to yield the fragments bPTH(1-41) and bPTH(42-84). These were then isolated by reverse-phase HPLC and characterised by gas-phase sequencing and amino acid analysis. The biological activities of these fragments were assessed in an adenylate cyclase bioassay using the rat osteosarcoma cell line UMR106. bPTH(1-41) was found to have approximately twice the molar potency of the native hormone from which it was derived. bPTH(42-84) had no biological activity and did not modulate the adenylate cyclase response to these cells to the native hormone. The possible physiological significance of these observations is discussed.
