R3H domain of Poly(A)-specific ribonuclease (PARN). PARN is a poly(A)-specific 3' exonuclease from the RNase D family that, in Xenopus, deadenylates a specific class of maternal mRNAs which results in their translational repression. The name of the R3H domain comes from the characteristic spacing of the most conserved arginine and histidine residues. The function of the domain is predicted to bind ssDNA or ssRNA.
