Sarcoplasmic reticulum Ca2+-pump density is higher in distal than in proximal segments of porcine left coronary artery
Abstract
Densities of sarcoplasmic reticulum (SR) Ca2+-pump were compared in proximal and distal segments of pig left coronary artery using two biochemical methods: acylphosphate formation and immunoreactivity in Western blots, and a functional assay based on contraction to SR Ca2+-pump inhibitors. In the microsomes prepared from smooth muscle, the level of the 115 kDa SR Ca2+-pump acylphosphate was 7.1 ± 0.3 -fold greater in distal than in proximal …
