Reports summarize life sciences study results from Kyoto University, Department of Biological Chemistry

New research, 'New molecular components supporting ryanodine receptor-mediated Ca(2+) release: roles of junctophilin and TRIC channel in embryonic cardiomyocytes,' is the subject of a report. "Ca(2+) mobilization from intracellular stores is mediated by Ca(2+) release channels, designated ryanodine and IP(3) receptors, and directly regulates important cellular reactions including muscle contraction, endo/exocrine secretion, and neural excitability. In order to function as an intracellular store, the endo/sarcoplasmic reticulum is equipped with cooperative Ca(2+) uptake, storage and release machineries, comprising synergic collaborations among integral-membrane, cytoplasmic and luminal...
