Abstract

Previously, we reported two types of vanadate-sensitive ATPases in the micro somes of tracheal epithelial cells, a high-affinity one and a low-affinity one. The low affinity vanadate-sensitive (LAVS) ATPase was sensitive to thapsigargin and cyclopiazonic acid, specific antagonists of ER-type Ca$\^$2＋/-ATPase, and mediated microsomal $\^$45/Ca$\^$2+/ uptake, implying that the LAVS-ATPase is an ER/SR-type Ca$\^$2+/-ATPase.(omitted)
