Can DNA-nanoparticle motors get up to speed with motor proteins?
DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion.
The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.
Storing and processing memories uses nanoscopic motor proteins called kinesin that move materials around within neurons to construct the structural code of memory. These nanoscopic workers “walk ...
The new finding is published in Cell in an article titled, “ SMC motor proteins extrude DNA asymmetrically and can switch directions ,” and is key to understanding how these motors shape our genome ...
We even identified the 'gear lever', protein subunit NIPBL, in the cohesin SMC motor protein." To discover the reverse gear of SMC motors, the researchers used an advanced home-built microscope ...
Spinal muscular atrophy is caused by mutations in the survival motor neurons gene, SMN1. The SMN protein localizes to both the cytoplasm and the nuclear bodies. One hallmark of spinal muscular ...
