It modulates the activities of proteins in nuclei, cytoplasm and mitochondria, regulates gene transcription and protein translation, trafficking and turnover, and contributes to various diseases such as diabetes mellitus, cancer, neurodegenerative and cardiovascular diseases24,28,29.
The detection of ITGB1 mRNA by RT-PCR suggests that the absence of ITGB1 protein on the RPMI 8866 cell surface is due to a failure in translation, trafficking, and/or maintenance/stability.
A reduction in the number of rescued progeny from the expected number was observed and could be due to altered expression, translation, trafficking, or biochemical activity of the fusion protein.
While we observed a slight reduction in the number of endogenous double knockdown, transgene-rescued progeny from the expected numbers based on Mendelian segregation, this could be a result of non-WT transgene expression or altered translation, trafficking, or activity of the tagged protein, resulting in some amount of embryonic lethality.
Ceftriaxone treatment however did not affect transporter translation, post-translational trafficking to and from the plasma membrane and transporter function within the membrane: we were unable to detect any alteration of EAAT2 expression after 5, 10 and 15 days of treatment refuting a time dependence of expression regulation seen in the study by Chu et al. [33].
There are several mechanisms by which a cell may achieve this, and they include altered transcription, translation, protein trafficking, post-translational modifications (PTMs) and, in particular, selective and limited cleavage at the plasma membrane, which controls the fate and activity of various cell surface proteins.
Arginine-rich motifs (ARMs) capable of binding diverse RNA structures play critical roles in transcription, translation, RNA trafficking, and RNA packaging.
Loxapine exhibited no effect, indicating that this mutation either caused the channel to be insensitive to this established opener or proper translation and trafficking to the membrane was disrupted.
It has been proposed that PfHsp70-1 withs witHsp9090 for parasite growth and development, possibly helps regulate the parasite's protein translation, and trafficking proteins into the apicoplast, a parasite organelle.
In current views, this partitioning phenomenon occurs through positive selection-mRNAs encoding signal sequence-bearing proteins are directed into the signal recognition particle pathway early in translation and trafficked as mRNA/ribosome/nascent polypeptide chain complexes to the ER.
