Plus end directed motor protein
WebKinesin-like protein KIF17 is a protein that in humans is encoded by the KIF17 gene. KIF17 and its close relative, C. elegans OSM-3, are members of the kinesin-2 family of plus-end directed microtubule-based motor proteins. In contrast to heterotrimeric kinesin-2 motors, however, KIF17 and OSM-3 form distinct homodimeric complexes. Homodimeric kinesin-2 … WebMicroscopy of live cells indicates that movement of membrane tubules can occur by three different mechanisms: (a) motor proteins pull on the membrane as they migrate along a …

WebSep 18, 2000 · The recent discovery that the class VI myosin is minus end-directed ( Schliwa 1999; Wells et al. 1999) allows new mechanisms of actin-based motility to exist in cells. This will prompt reexamination of a broad range of cell movements previously difficult to explain by conventional force generating mechanisms. WebHere, we report the observation that ATK5 is a minus-end–directed motor as well as a plus-end tracking protein (+TIP). We show that ATK5 is a mitotic motor based on its localization to mitotic spindle midzones and the abnormal spindle morphology observed in …
The wide variety of myosin genes found throughout the eukaryotic phyla were named according to different schemes as they were discovered. The nomenclature can therefore be somewhat confusing when attempting to compare the functions of myosin proteins within and between organisms. Skeletal muscle myosin, the most conspicuous of the myosin superfamily due … Webtransmembrane helices, plus homology to the rhodopsin sequence (35-37) within several of the transmembrane spans (33).

WebDec 15, 2006 · Eg5, a member of the Kinesin-5 subclass of kinesins, is a plus-end-directed tetrameric kinesin-family protein that influences the assembly and organization of the mitotic spindle, a self-assembled and dynamic microtubule-based structure that orchestrates chromosome segregation in dividing cells (Figure 1) [ 1 3 ]. WebJan 1, 2024 · These proteins belong to two families – the kinesin-related proteins (such as kinesin-5, kinesin-14, kinesin-4, and kinesin-10) and dynein. 6. Kinesin-5 protein (plus end-directed motor protein) interacts with the plus ends of antiparallel polar microtubules in the spindle midzone and pushes the poles apart.
WebDec 30, 1994 · This N-terminal-type motor protein is expressed ubiquitously in various kinds of tissues. In situ hybridization revealed that KIF1B is expressed abundantly in differentiated nerve cells. Interestingly, KIF1B works as a monomer, having a microtubule plus end-directed motility.
