Abstract

Myosin Minireview Series

Highlights

  • It was initially thought that detailed studies of contractile proteins from striated muscles would provide a basis for understanding many nonmuscle contractile and motility events because conventional myosins were found in most eukaryotic cells (14)

  • Chain subunit by a dedicated Ca2ϩ/calmodulin-dependent myosin light chain kinase, which markedly increases actin-activated myosin ATPase activity (19, 20). Another hint of differences in the myosin motor family came from the observation that Acanthamoeba contained a small, singleheaded myosin (21)

  • The myosin head or motor domain is highly conserved, which contributed to the successful hunt for new myosin motors by the polymerase chain reaction

Introduction
