Background
This gene encodes a component of the telomerase ribonucleoprotein complex responsible for the replication and maintenance of chromosome ends. The encoded protein also plays a role in the nonsense-mediated mRNA decay (NMD) pathway, providing the endonuclease activity near the premature translation termination codon that is needed to initiate NMD. Alternatively spliced transcript variants encoding distinct protein isoforms have been described.

Interaction
May form homooligomers (PubMed:20930030). Associated component of the telomerase holoenzyme complex (PubMed:19179534). Interacts with TERT, independently of the telomerase RNA (PubMed:12676087, PubMed:12699629). Interacts with SMG1, SMG5, SMG7, UPF1, UPF2, UPF3B and the PP2A catalytic subunits (PubMed:12554878, PubMed:19060897, PubMed:20930030). Also interacts with the exon junction complex (EJC) composed at least of CASC3, EIF4A3, MAGOH and RBM8A; required for the process of nonsense-mediated mRNA decay (PubMed:20930030). Interacts with DHX34; the interaction is RNA-independent (PubMed:25220460).
