About TARBP2

Cytogenetic location: 12q13.13 Genomic coordinates (GRCh38): 12:53,500,923-53,506,431 (from NCBI)

This gene has 20 transcripts (splice variants), 211 orthologues and 14 paralogues. Ubiquitous expression in placenta (RPKM 7.8), testis (RPKM 6.1) and 25 other tissues.

Summary

HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. The protein encoded by this gene binds between the bulge and the loop of the HIV-1 TAR RNA regulatory element and activates HIV-1 gene expression in synergy with the viral Tat protein. Alternative splicing results in multiple transcript variants encoding different isoforms. This gene also has a pseudogene. [provided by RefSeq, Jul 2008]
