======= HTATSF1 ======= == Gene Information == * **Official Symbol**: HTATSF1 * **Official Name**: HIV-1 Tat specific factor 1 * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=27336|27336]] * **UniProt**: [[https://www.uniprot.org/uniprot/O43719|O43719]] * **Interactions**: [[https://thebiogrid.org/search.php?search=HTATSF1&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20HTATSF1|Open PubMed]] * **OMIM**: [[https://omim.org/entry/300346|Open OMIM]] == Function Summary == * **Entrez Summary**: The protein encoded by this gene functions as a cofactor for the stimulation of transcriptional elongation by HIV-1 Tat, which binds to the HIV-1 promoter through Tat-TAR interaction. This protein may also serve as a dual-function factor to couple transcription and splicing and to facilitate their reciprocal activation. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Sep 2009]. * **UniProt Summary**: Functions as a general transcription factor playing a role in the process of transcriptional elongation. May mediate the reciprocal stimulatory effect of splicing on transcriptional elongation. In case of infection by HIV-1, it is up-regulated by the HIV-1 proteins NEF and gp120, acts as a cofactor required for the Tat-enhanced transcription of the virus. {ECO:0000269|PubMed:10393184, ECO:0000269|PubMed:10454543, ECO:0000269|PubMed:10913173, ECO:0000269|PubMed:11420046, ECO:0000269|PubMed:11780068, ECO:0000269|PubMed:15905670, ECO:0000269|PubMed:8849451, ECO:0000269|PubMed:9765201}. |RRM 1| |U2-type spliceosomal complex| |U2 snRNP| |viral genome replication| |regulation of DNA-templated transcription, elongation| |viral life cycle| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions| |RNA splicing| |mRNA processing| |mRNA metabolic process| |viral process| |symbiotic process| |interspecies interaction between organisms| |RNA processing| |RNA binding| |RNA metabolic process| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp539|42°C R08 exp539]]|-2.34| |[[:results:exp350|Deferoxamine 11μM R07 exp350]]|-1.99| |[[:results:exp532|TIC10 10μM R08 exp532]]|-1.99| |[[:results:exp513|ONC212 0.15μM R08 exp513]]|-1.97| |[[:results:exp439|QNZ 0.01μM R08 exp439]]|-1.75| |[[:results:exp144|PFI-3 10μM R03 exp144]]|1.84| ^Gene^Correlation^ |[[:human genes:t:terf1|TERF1]]|0.449| |[[:human genes:t:tfip11|TFIP11]]|0.436| |[[:human genes:a:atp6v1c1|ATP6V1C1]]|0.432| |[[:human genes:s:sf3a2|SF3A2]]|0.431| |[[:human genes:t:tbc1d3g|TBC1D3G]]|0.42| |[[:human genes:t:tbc1d3c|TBC1D3C]]|0.404| |[[:human genes:p:psma6|PSMA6]]|0.404| |[[:human genes:t:tceb3cl2|TCEB3CL2]]|0.403| |[[:human genes:k:kctd17|KCTD17]]|0.403| Global Fraction of Cell Lines Where Essential: 515/694 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|1/1| |bile duct|17/28| |blood|22/26| |bone|23/26| |breast|19/30| |central nervous system|32/49| |cervix|4/4| |colorectal|12/17| |esophagus|7/11| |fibroblast|1/1| |gastric|8/14| |kidney|12/18| |liver|13/19| |lung|52/72| |lymphocyte|14/16| |ovary|19/25| |pancreas|18/22| |peripheral nervous system|13/15| |plasma cell|10/12| |prostate|1/1| |skin|18/20| |soft tissue|9/9| |thyroid|1/2| |upper aerodigestive|16/22| |urinary tract|17/28| |uterus|4/5| == Essentiality in NALM6 == * **Essentiality Rank**: 459 * **Expression level (log2 read counts)**: 6.51 {{:chemogenomics:nalm6 dist.png?nolink |}}
