InterPro domain: IPR036189

General Information

  • Identifier IPR036189
  • Description mRNA decapping protein 2, Box A domain superfamily

Abstract

This superfamily represents the box A specific to mRNA decapping protein 2 P53550 , Dcp2, the catalytic subunit of the mRNA-decapping enzyme [ 1 ], which is found at the N-terminal of the NUDIX hydrolase domain IPR000086 . Removal of the cap structure is mediated by the Dcp1-Dcp2 complex [ 2 ].

The Box A domain contains a four helices fold and an orthogonal array of two alpha hairpins topology.
