Crystal Structure of the DEAD box protein Dhh1pCrystal Structure of the DEAD box protein Dhh1p

Structural highlights

1s2m is a 1 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.1Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

DHH1_YEAST ATP-dependent RNA helicase involved in mRNA turnover, and more specifically in mRNA decapping by activating the decapping enzyme DCP1. Is involved in G1/S DNA-damage checkpoint recovery, probably through the regulation of the translational status of a subset of mRNAs. May also have a role in translation and mRNA nuclear export. Required for sporulation.[1] [2] [3] [4] [5] [6] [7] [8] [9]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
