The exosome-binding factors Rrp6 and Rrp47 form a composite surface for recruiting the Mtr4 helicase.
Title: The exosome-binding factors Rrp6 and Rrp47 form a composite surface for recruiting the Mtr4 helicase.
Rrp47p reduces the exonucleolytic activity of Rrp6p on both single-stranded and structured RNA substrates without significantly altering the affinity towards RNA or the ability of Rrp6p to degrade RNA secondary structure.

Rrp47 and Rrp6 have resolvable functions in Rrp6-mediated RNA surveillance and processing pathways.
Title: Rrp47 functions in RNA surveillance and stable RNA processing when divorced from the exoribonuclease and exosome-binding domains of Rrp6.

both the C terminus of Rrp47 and the N-terminal domain contribute to its RNA-binding activity.
Title: The C-terminal region of the exosome-associated protein Rrp47 is specifically required for box C/D small nucleolar RNA 3'-maturation.
Results suggest Rrp47p promotes Rrp6p activity by facilitating binding via the PMC2NT domain to structural elements within RNA.
Title: The PMC2NT domain of the catalytic exosome subunit Rrp6p provides the interface for binding with its cofactor Rrp47p, a nucleic acid-binding protein.
Lrp1 mediates specific mRNA degradation upon DNA-damaging UV irradiation as well as general mRNA degradation
