TREX1

MIM.606609 3p21.3-p21.2

Friday 16 March 2007

The multistep processes of DNA replication, repair, and recombination require the excision of nucleotides from DNA 3-prime termini.

TREX1 constitutes the major 3’—>5’ DNA exonuclease activity measured in mammalian cells. Enzymes containing 3-prime-to-5-prime exonuclease activity, such as TREX1, remove mismatched, modified, fragmented, and normal nucleotides to generate the appropriate 3-prime termini for subsequent steps in the DNA metabolic pathways.

TREX1 has 2 coiled-coil domains and multiple sites for potential phosphorylation by ATR (MIM.601215) or ATM (MIM.607585). ATRIP and ATR are mutually dependent partners in cell cycle signaling pathways.
