Protein existence	Evidence at protein level

General annotation (Comments)

Function	Major 5'-3' exoribonuclease involved in mRNA decay. Required for the 5'-3'-processing of the G4 tetraplex-containing DNA and RNA substrates. The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds to RNA and DNA By similarity. Plays a role in replication-dependent histone mRNA degradation. May act as a tumor suppressor protein in osteogenic sarcoma (OGS). Ref.8 Ref.10
Subunit structure	Associates with alpha and beta tubulins By similarity. Found in a mRNP complex with UPF1, UPF2, UPF3B and XRN1.
Subcellular location	Cytoplasm. Note: Discrete foci at the inner surface of the cell membrane. Ref.1 Ref.5 Ref.7
Tissue specificity	Expressed in heart, brain, pancreas, spleen, testis, osteogenic sarcoma (OGS) biopsy and primary cell lines. Ref.8
Induction	By GDNF/glial cell line-derived neurotrophic factor. Ref.1
Miscellaneous	Down-regulated in OGS biopsy.
Sequence similarities	Belongs to the 5'-3' exonuclease family.
