Example sentences for: polyribosomes

How can you use “polyribosomes” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • However, sucrose gradient analyses of the post- mitochondria fraction showed that, unlike DAZL, DAZAP1 did not co-sediment with polyribosomes (Figure 6).

  • This finding is different from two RNA-binding proteins, FXR1P and FXR2P, that were identified through their interaction with another polysomal-associated RNA-binding protein, the fragile X mental retardation protein [ 21 ] . Both FXR1P and FXR2P are associated with the polyribosomes [ 22 ] .

  • Its absence from polyribosomes indicates that it is not directly involved in mRNA translation.

  • RNA-binding proteins have been found to participate in many cellular functions, including RNA transcription, pre-mRNA processing, mRNA transport, localization, translation and stability [ 20 ] . A role for the DAZ family in the regulation of mRNA translation is supported by lines of circumstantial evidence, including the association of DAZL with polyribosomes [ 12 ] . The absence of DAZAP1 from polyribosomes indicates that it is not directly involved in protein synthesis.

  • Our previous fractionation of mouse testis extracts showed that most DAZL were present in the post mitochondrial fraction, and some of them were associated with polyribosomes [ 12 ] . Similar analyses showed that a majority of DAZAP1 in adult mouse testes was also present in the cytoplasmic fraction (data not shown).
