Scavenger mRNA-decapping enzyme DcpS is a protein that in humans is encoded by the DCPS gene.The scavenger mRNA decapping enzymes include Dcp2 and DcpS. DcpS is a scavenger pyrophosphatase that hydrolyses the residual cap structure following 3′ to 5′ mRNA degradation. DcpS uses cap dinucleotides or capped oligonucleotides as substrates to release m(7)GMP (N7-methyl GMP) while Dcp2 uses capped mRNA as a substrate in order to hydrolyse the cap to release m(7)GDP (N7-methyl GDP).
