However, there was no effect on DISC1 localization upon mutating the relevant leucine residues to alanines in both sites, regions 502-CDLTPLVGQLSLGQ-515 and 619-EGLEGLLSKLLVLSS-633.
Cys-less CFTR was constructed by mutating the 18 endogenous cysteines to alanine or leucine.
Mutating the distal, helix-destabilizing G143 residue to leucine shifted cleavage site −1 residues outwards.
Mutating the fourth amino acid from the uncharged, polar, hydrophilic serine to an uncharged, hydrophobic leucine has shown an increased stability of the mutant protein by showing higher protein levels found in the cytoplasm and mitochondrial fractions.
pGL3 misincorporation test reporters (pGL3m2) was created by mutating the firefly luciferase catalytic residue R218 from the wild-type AGA codon to the near-cognate AGC leucine codon of the pGL3 vector.
The misincorporation test reporters were created by mutating the firefly luciferase catalytic residue R218 from the wild-type AGA codon to either the near-cognate AGC leucine codon, or the non-cognate TCT leucine codon, so that active firefly luciferase can only synthesized when the incorrect tRNAArg is selected.
That furthered my sense of mutating the genres.
To show that co-import of LDHA is dependent on the hidden targeting signal in LDHBx, we mutated the targeting signal to SSI, or we deleted the terminal leucine.
HEK293 cells were transiently transfected with IGF1R-fl wild-type (WT), IGF1R-fl bearing P911L mutation (P911L), isoleucine substitutions to the alanine residues either side of P911 (IxPxI), or the same with the proline mutated to leucine (IxLxI), or not transfected (U).
After we had determined the minimum amount of residues required to yield a functional recombinant protein, we mutated the amino acid on the truncation of which the activity was lost, a leucine residue, in a larger construct to investigate whether we simply required a certain length of the protein, or whether specific residues were needed.
