Polysome - Wikipedia
网页Polysome. A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like “beads” on a “thread”. [1] It consists of a complex of an mRNA molecule and two or more ribosomes that act to translate mRNA …
Polysome - an overview | ScienceDirect Topics
网页Polysomes are stable protein–ribosome–mRNA complexes, which can be used to replace live bacteriophages as the display vehicle for recombinant antibody fragments [74•,75]. The polysomes are formed by preventing release of newly synthesised and correctly folded protein from the ribosome.
Analysis of translation using polysome profiling - PubMed
网页2017年2月17日 · Polysome profiling has been developed to infer the translational status of a specific mRNA species or to analyze the translatome, i.e. the subset of mRNAs actively translated in a cell. Polysome profiling is especially suitable for emergent model organisms for which genomic data are limited.
Polysome - Vocab, Definition, and Must Know Facts - Fiveable
网页A polysome, also known as a polyribosome, is a complex formed by multiple ribosomes simultaneously translating a single mRNA strand. This structure allows for the efficient synthesis of many copies of a protein from one mRNA molecule.
10.7: Eukaryotic Translation - Biology LibreTexts
网页2022年12月30日 · Technically, a polysome is simply an mRNA with multiple ribosomes translating it simultaneously, but in eukaryotes, the polysome also has a unique morphology because it utilizes PABPI, or poly-A binding protein.
Polysomes, Stress Granules, and Processing Bodies: A Dynamic ...
网页2017年11月20日 · The export of an mRNA from the nucleus to the cytoplasm begins an odyssey of dynamic regulation that determines the location, longevity, and use of the transcript in the production of polypeptides by ribosomes in plant cells.
Polysome Analysis - PMC - National Center for Biotechnology ...
网页2017年3月3日 · Polysome analysis is a method to separate mRNAs from a cell into actively translating and non-translating fractions depending on their association with polysomes. By this protocol, cell lysates are fractionated by sucrose density gradient ultracentrifugation.
