Pcna s phase

Splet19. maj 2015 · A major challenge in deriving an association of the AC‐13 pattern with antibodies to the classical 35 kDa PCNA (elongation factor of DNA polymerase delta auxiliary protein) is that “PCNA” is known to be a macromolecular complex where targets other than the ‘classical’ 35 kDa PCNA are present. Splet01. sep. 2006 · We have shown recently ( Hoege et al., 2002) that PCNA can be modified in S phase by monoubiquitin, a multiubiquitin chain, or SUMO. Ubiquitylation, triggered by DNA damage, occurs at lysine K164 of PCNA and promotes two types of replicative DNA damage bypasses ( Hoege et al., 2002, Stelter and Ulrich, 2003 ).
