Exosome RNA helicase MTR4 (MTREX)

Part of exosome targeting complexes. Subunit of the trimeric nuclear exosome targeting (NEXT) complex, a complex that directs a subset of non-coding short lived RNAs for exosomal degradation.

Subunit of the trimeric poly(A) tail exosome targeting (PAXT) complex, a complex that directs a subset of extended and polyadenylated poly(A) RNAs for exosomal degradation. The RNA exosome is fundamental for the degradation of RNA in eukaryotic nuclei.
