Family-specific Kinesin Structures Reveal Neck-linker Length Based on Initiation of the Coiled-coil.
Kinesin-1, -2, -5, and -7 generate processive hand-over-hand 8-nm steps to transport intracellular cargoes toward the microtubule plus end. This processive motility requires gating mechanisms to coordinate the mechanochemical cycles of the two motor heads to sustain the processive run. A key structural element believed to regulate the degree of processivity is the neck-linker, a short peptide o...
متن کاملThe coiled-coil helix in the neck of kinesin.
Kinesin is a microtubule-dependent motor protein. We have recently determined the X-ray structure of monomeric and dimeric kinesin from rat brain. The dimer consists of two motor domains, held together by their alpha-helical neck domains forming a coiled coil. Here we analyze the nature of the interactions in the neck domain (residues 339-370). Overall, the neck helix shows a heptad repeat (abc...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولNeck Linker Length Determines the Degree of Processivity in Kinesin-1 and Kinesin-2 Motors
Defining the mechanical and biochemical determinates of kinesin processivity is important for understanding how diverse kinesins are tuned for specific cellular functions. Because transmission of mechanical forces through the 14-18 amino acid neck linker domain underlies coordinated stepping, we investigated the role of neck linker length, charge, and structure in kinesin-1 and kinesin-2 motor ...

Defining the mechanical and biochemical determinates of kinesin processivity is important for understanding how diverse kinesins are tuned for specific cellular functions. Because transmission of mechanical forces through the 14–18 amino acid neck linker domain underlies coordinated stepping [1–6], we investigated the role of neck linker length, charge, and structure in kinesin-1 and kinesin-2 ...
