KRAB-associated protein-1
Background
TRIM28 (KAP1, KRAB-associated protein 1) is co-repressor for KRAB-zinc-finger proteins, mediating epigenetic silencing, DNA-damage response and retrotransposon repression. Acting as molecular scaffold, KAP1 recruits HDAC, SETDB1 and other epigenetic effector complexes to deposit repressive H3K9me3 marks, driving heterochromatin assembly and silencing endogenous retroviruses (ERV). KAP1 phosphorylation relieves its repressive activity.
