Example sentences for: posttranslational

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

  • These posttranslational lipid modifications are essential for attachment of the GTPases to the cytosolic face of intracellular vesicles and/or to the cytosolic leaflet of the plasma membrane, thereby specifying subcellular targets for GTPase action(s).

  • Previous studies have demonstrated that posttranslational modifications of RARs and RXRs are critical to the biological activity of the receptors.

  • The polypeptide precursor of CT, pre-procalcitonin, undergoes cleavage of its leader sequence early in posttranslational processing to yield ProCT, and several constituent peptides (Fig 1).

  • Regulation of EPK function can occur at many levels, including control of synthesis, posttranslational modification, binding of regulatory proteins and subcellular localization.

  • Rab proteins comprise a large family of Ras-related GTPases that function in the anterograde and retrograde trafficking of proteins in mammalian cells [ 1 2 3 ] . Different Rab proteins reside in specific subcellular membranes or organelles, where they mediate vesicular transport between discrete donor and acceptor compartments in the endocytic or exocytic pathways [ 4 5 ] . Detailed studies of a few Rab proteins ( e.g .; Rab1, Rab5 and Rab9) have led to a general model wherein Rab proteins are presumed to cycle on and off donor and acceptor membranes in connection with changes in their guanine nucleotide state [ 6 7 8 ] . In the active GTP-bound state, Rab proteins associate with budding transport vesicles [ 9 10 11 ] and appear to participate in the assembly of membrane docking complexes [ 12 13 14 ] . Following vesicle fusion with the acceptor compartment and GTP hydrolysis, the inactive GDP-bound Rab is extracted from the membrane by a carrier protein termed guanine nucleotide dissociation inhibitor (GDI) [ 15 16 17 ] . The GTPase can then re-enter the transport cycle through nucleotide exchange promoted by a specific exchange factor at the donor vesicle membrane [ 18 19 20 ] . In addition to changes in guanine nucleotide state, the posttranslational prenylation of Rab proteins plays an important role in the cycling mechanism.
