How come dynein runs faster and longer when loaded with an RNA cargo? New in vitro single-molecule assays and electron microscopy reveal molecular mechanisms
Selected by Dmitry NashchekinCategories: biochemistry, cell biology, developmental biology, molecular biology
Summary
Cytoplasmic dynein-1 (dynein) is an essential motor complex for mRNA transport and localisation. Motor activity of dynein is regulated by cargo adaptor proteins1,2, but whether mRNA could influence the efficiency of dynein as well has remained unclear. These two preprints from the Bullock and Trybus labs show that mRNA could work as a scaffolding structure bringing together adaptor and motor proteins. Only when all components are in place is dynein switched on and able to work as a full power motor. These studies provide a new paradigm of how mRNA and probably other cargos could stimulate their own transport.
Key findings and bigger picture
The authors follow up on previous observations that the dynein/dynactin complex exists in an autoinhibitory state and requires adaptor proteins and cargos to be converted to a highly processive motor. With the help of a new single molecule RNA transport assay from the purified components (McClintock et al. and Sladewski, Billington, Ali et al.) paired with electron microscopy (Sladewski, Billington, Ali et al.), the authors are able to offer a new model for the regulation of dynein transport. They provide molecular mechanisms of how the presence of a localisation signal on mRNA could be converted, through adaptor proteins, to the activity of the motor. Interestingly, Sladewski et al. also show that the speed of the RNA transport could be regulated not only by the dynein activity per se but also by the number of motors attracted to the cargo. This observation fits very nicely with the recent structural studies showing that adaptor proteins make transport faster by recruiting two dyneins at the cargo3,4.
Open questions
It will be interesting to see whether other types of dynein cargos (e.g. vesicles) could influence transport in a similar way.
In the transport assay, authors were able to achieve only half of the normal dynein speed. It would be exciting to find out what were the missing components that could stimulate dynein even further.

Peer Review in Biomedical Sciences
Communication of scientific knowledge has changed dramatically in recent decades and the public perception of scientific discoveries depends on the peer review process of articles published in scientific journals. Preprints are key vehicles for the dissemination of scientific discoveries, but they are still not properly recognized by the scientific community since peer review is very limited. On the other hand, peer review is very heterogeneous and a fundamental aspect to improve it is to train young scientists on how to think critically and how to evaluate scientific knowledge in a professional way. Thus, this course aims to: i) train students on how to perform peer review of scientific manuscripts in a professional manner; ii) develop students' critical thinking; iii) contribute to the appreciation of preprints as important vehicles for the dissemination of scientific knowledge without restrictions; iv) contribute to the development of students' curricula, as their opinions will be published and indexed on the preLights platform. The evaluations will be based on qualitative analyses of the oral presentations of preprints in the field of biomedical sciences deposited in the bioRxiv server, of the critical reports written by the students, as well as of the participation of the students during the preprints discussions.
