Meeting Abstract P1.75  Jan. 4  Extraocular Muscle Myosin and the Origin of Modern Vertebrate Myosins BRIGGS, M.M.; SCHACHAT, F.H.*; Duke Univ. Med. Ctr.; Duke Univ, Med. Ctr. m.briggs@cellbio.duke.edu The extraocular muscle (EOM) myosin heavy chain gene (MYH13) is the precursor of “modern” vertebrate striated muscle myosins. EOM myosin is expressed only in EOM and laryngeal muscle of […]
