    The mechanism underlying transient weakness in myotonia congenita

    Jessica H Myers, Kirsten Denman ... Mark M Rich
    Transient weakness in myotonia congenita is caused by depolarization secondary to activation of persistent Na+ current in skeletal muscle.

    Dual interaction of scaffold protein Tim44 of mitochondrial import motor with channel-forming translocase subunit Tim23

    See-Yeun Ting, Nicholas L Yan ... Elizabeth A Craig
    The motor that drives preproteins into the mitochondrial matrix is coupled to the translocase by Tim44, a two-domain scaffold protein with an intrinsically disordered "dynamic arm" and a structurally stable anchoring domain.
