Summary: This gene encodes a protein containing tetratricopeptide repeats that was originally identified as induced upon treatment with interferon. The encoded protein may inhibit viral replication and translational initiation. This gene is located in a cluster on chromosome 10 with five other closely related genes. There is a pseudogene for this gene on chromosome 13. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Aug 2012]
Expression: Ubiquitous expression in adrenal (RPKM 10.7), spleen (RPKM 10.7) and 25 other tissues See more

The results uncovered a large ensemble of RNA secondary structures of diverse size and shape in the different viruses, which showed little correspondence to the phylogeny of the viruses. Unexpectedly, the 50UTR of several viral genomes in this family did not fold into any structure, suggesting either their extreme sensitivity to IFIT1 or the existence of alternative viral mechanisms of subverting IFIT1 function.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
