Example sentences for: mycrab
How can you use “mycrab” in a sentence? Here are some example sentences to help you improve your vocabulary:
Rab24 contains a unique arginine-rich insert, 126EEDRRRRR 133 [ 25 ] in the domain cognate to loop-8 in H-Ras [ 34 ] . The latter sequence is reminiscent of unusual arginine-rich nuclear localization signals that allow proteins like HIV tet and rev to undergo nuclear translocation by association with importin-β, in the absence of importin-α [ 45 46 ] . Since the loop-8 insert in Rab24 lies adjacent to the conserved N(T)KxD nucleotide binding cassette, we hypothesized that conformational changes caused by the D123I substitution might render the Rab24 mutant capable of disrupting the nuclear import machinery [ 47 ] . To test this possibility, we co-expressed mycRab24wt or mycRab24(D123I) with GR-GFP, a fusion between the glucocorticoid receptor and green fluorescent protein.
To assess the guanine nucleotide state of selected mycRab24 proteins, cells were transfected with the indicated constructs and incubated with 32P-orthophosphate for 5 h, starting 24 h after transfection.
Cells were transfected with pCMV5 expression vectors encoding mycRab24(D123I) as described earlier.
Such structures were never observed in cells expressing mycRab24wt or any other over-expressed Rab GTPase.
Although Rab24 has been proposed as a possible regulator of autophagic processes [ 24 43 ] , the accumulation of punctate bodies in cells expressing Rab24(D123I) was not prevented by 3-methyadenine, a known inhibitor of autophagosome formation [ 44 ] . Most importantly, electron microscopy with immunogold labeling of mycRab24(D123I) in ultra-thin sections confirmed the initial impression that the inclusions are in fact localized within the nucleus.
