Farnesylation of proteins
WebAug 12, 2004 · Protein farnesylation is a posttranslational modification involving the covalent attachment of a 15-carbon farnesyl isoprenoid through a thioether bond to a cysteine residue near the C terminus of proteins in a conserved farnesylation motif designated the “CAAX box,” where “C” is a cysteine residue, “A” as an aliphatic residue, … WebAnother interpretation is that FTIs simply strengthen the bones in the progeria mice by some unrelated mechanism (i.e. involving another farnesylated protein), leading to a global improvement in the health of the mice. Finding out whether FTIs actually improve disease directly by interfering with prelamin A farnesylation is an important issue ...
