    A Darier disease mutation relieves kinetic constraints imposed by the tail of sarco(endo)plasmic reticulum Ca-ATPase 2b.
    J Biol Chem 2018 Jan 23. Epub 2018 Jan 23.
    Dept. Biomedicine, Aarhus University/Denmark, Denmark.
    The sarco(endo)plasmic reticulum Ca-ATPase (SERCA) 2b isoform possesses an extended C terminus (SERCA2b tail) forming an 11th transmembrane (TM) helix, which slows conformational changes of the Ca-pump reaction cycle. Here, we report that a Darier disease (DD) mutation of SERCA2b that changes a glutamate to lysine in the cytoplasmic loop between TM8 and TM9 (E917K) relieves these kinetic constraints. We analyzed the effects of this mutation on the overall reaction and the individual partial reactions of the Capump compared with the corresponding mutations of the SERCA2a and SERCA1a isoforms lacking the SERCA2b tail.
