In case of infection by HIV-1, it binds to the loop region of TAR RNA, a region also bound by RNA polymerase II. Binding of TARBP1 and RNA polymerase II to HIV-1 TAR RNA is mutually exclusive, suggesting that TARBP1 may function alone or in conjunction with HIV-1 Tat to disengage RNA polymerase II from HIV-1 TAR RNA. May act by methylating HIV-1 TAR RNA. {ECO:0000269|PubMed:7638159, ECO:0000269|PubMed:8626763, ECO:0000269|PubMed:8846792}. |SpoU methylase| |tRNA (guanine) methyltransferase activity| |tRNA methylation| |RNA methylation| |tRNA modification| |tRNA processing| |RNA modification| |tRNA metabolic process| |macromolecule methylation| |methylation| |ncRNA processing| |ncRNA metabolic process| |RNA processing| |RNA binding| |RNA metabolic process| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp357|Dorsomorphin 5μM R07 exp357]]|1.74| |[[:results:exp289|Hydroxyurea 15μM R06 exp289]]|1.8| |[[:results:exp360|Genistein 15μM R07 exp360]]|1.81| ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.548| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 17817 * **Expression level (log2 read counts)**: 7.21 {{:chemogenomics:nalm6 dist.png?nolink |}}
