How can you use “rab” in a sentence? Here are some example sentences to help you improve your vocabulary:
Oligonucleotide primers for the PCR reaction were based on the published sequence of murine Rab24 [ 24 ] . Kpn1 and BamH1 restriction sites were added to the 5' and 3' primers respectively, to facilitate cloning of the PCR product in frame with a 5' sequence cassette encoding a myc epitope (EQKLISEEDL), previously introduced into the pCMV5 expression vector [ 78 ] . The Rab24 cDNA was altered by overlap-extension PCR [ 79 ] , using appropriate mutator oligonucleotides and Pfu DNA polymerase (Stratagene Inc., La Jolla, CA), so as to introduce amino acid substitutions at D123 (D123I), T120 (T120A), S22 (S22N), S67 (S67Q), and a deletion of residues 127 through 130 (ΔEDRR).
Here we have shown that single amino acid substitutions ( e.g. , D123I and T120A) in one of the conserved guanine nucleotide binding domains of Rab24 can cause the protein to accumulate in a massive array of nuclear inclusions in mammalian cells.
Thus, the question of whether the nuclear inclusions containing the D123I and T120A mutants are caused by dominant-negative suppression of endogenous Rab24 function remains to be resolved.
In Rab24, and in some members of the Rho family, threonine occurs instead of the asparagine.
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.
