Abstract:
:Studies were made on the mechanism of the effect of parathyroid hormone (PTH) on the activity of (Ca2++Mg2+)-ATPase, a membrane bound Ca2+-extrusion pump enzyme from the basolateral membranes (BLM) of canine kidney (Km for free Ca2+ = 1.3 X 10(-7) M, Vmax = 200 nmol Pi/mg/min). At 1 X 10(-7) M free Ca2+, both PTH (10(-7)-10(-6) M) and cAMP (10(-6)-10(-4) M) stimulated (Ca2++Mg2+)-ATPase activity dose-dependent and their stimulatory effects were inhibited completely by 5 microM H-8, an inhibitor of cAMP-dependent protein kinase. PTH (10(-7) M) also caused 40% increase in 32P incorporation into the BLM and 5 microM H-8 inhibited this increase too. PTH (10(-7) M) was found to stimulate phosphorylation of a protein of Mr 9000 by cAMP dependent protein kinase and 5 microM H-8 was found to block this stimulation also. From these results, it is proposed that PTH stimulates (Ca2++Mg2+)-ATPase activity by enhancing its affinity for free Ca2+ via cAMP-dependent phosphorylation of a BLM protein of Mr 9000.
