DHX8 - DEAH-box helicase 8 Gene
Also Known as DDX8; Dhr2; HRH1; PRP22; PRPF22
Species: Homo sapiens
About DHX8
This gene has 9 transcripts (splice variants), 219 orthologues and 18 paralogues. Ubiquitous expression in bone marrow (RPKM 10.3), testis (RPKM 7.7) and 25 other tissues.
Summary
This gene is a member of the DEAH box polypeptide family. The encoded protein contains the DEAH (Asp-Glu-Ala-His) motif which is characteristic of all DEAH box proteins, and is thought to function as an ATP-dependent RNA helicase that regulates the release of spliced mRNAs from spliceosomes prior to their export from the nucleus. This protein may be required for the replication of human immunodeficiency virus type 1 (HIV-1). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]
