  • Title: Ion pathways in proteins of the sarcoplasmic reticulum.
    Author: MacLennan DH, Reithmeier RA, Shoshan V, Campbell KP, LeBel D, Herrmann TR, Shamoo AE.
    Journal: Ann N Y Acad Sci; 1980; 358():138-48. PubMed ID: 6259987.
    Abstract:
    In summary, we have begun to characterize three different ion pathways in the sarcoplasmic reticulum. Ca2+-ionophoric activity has been traced to a 13,000-dalton CNBr fragment localized at the amino terminus of the ATPase molecule... The pathway involved in Ca2+ release can be distinguished from the pathway involved in Ca2+ uptake by its insensitivity to quercetin. An anion pathway is sensitive to DIDS and appears to be localized in the ATPase molecule
