Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder due to a LMNA gene mutation which produces a mutant lamin A protein (progerin). Progerin also has been correlated to physiological aging and related diseases. However, how progerin causes the progeria remains unknown. Here we report that the large subunit (RFC1) of replication factor C is cleaved in HGPS cells, leading to the production of a truncated RFC1 of ~75 kDa which appears to be defective in loading PCNA and pol δ onto DNA for replication. Interestingly, the cleavage can be inhibited by a serine protease inhibitor, suggesting that RFC1 is cleaved by a serine protease. Due to the crucial role of RFC in DNA replication our findings provide a mechanistic interpretation for the observed replicative arrest and premature aging phenotypes of HPGS, and may lead to novel strategies in HGPS treatment. Furthermore, this unique truncated form of RFC1 may serve as a potential marker for HGPS.
