Binds rDNA promoters and plays a role in Pol I recruitment as a component of the SL1/TIF-IB complex and, possibly, directly through its interaction with RRN3. {ECO:0000269|PubMed:15970593, ECO:0000269|PubMed:21921198, ECO:0000269|PubMed:21921199, ECO:0000269|PubMed:7491500, ECO:0000269|PubMed:7801123, ECO:0000269|PubMed:7801130}. |RRN7| |RNA polymerase I core factor complex| |RNA polymerase transcription factor SL1 complex| |nucleolar large rRNA transcription by RNA polymerase I| |RNA polymerase I CORE element sequence-specific DNA binding| |RNA polymerase I preinitiation complex assembly| |rRNA transcription| |TBP-class protein binding| |transcription elongation from RNA polymerase I promoter| |transcription preinitiation complex assembly| |termination of RNA polymerase I transcription| |transcription initiation from RNA polymerase I promoter| |transcription by RNA polymerase I| |positive regulation of gene expression, epigenetic| |DNA-templated transcription, termination| |DNA-templated transcription, elongation| |ncRNA transcription| |protein-DNA complex assembly| |DNA-templated transcription, initiation| |regulation of gene expression, epigenetic| |protein-DNA complex subunit organization| |transcription, DNA-templated| |nucleic acid-templated transcription| |RNA biosynthetic process| |cellular protein-containing complex assembly| |nucleobase-containing compound biosynthetic process| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |organic cyclic compound biosynthetic process| |protein-containing complex assembly| |cellular nitrogen compound biosynthetic process| |RNA metabolic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |protein-containing complex subunit organization| |positive regulation of gene expression| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp27|Pimelic-diphenylamide-106 0.5μM R00 exp27]]|-2.08| |[[:results:exp131|L-74142 5μM R03 exp131]]|-1.73| |[[:results:exp466|Cannabidiol 20μM R08 exp466]]|2.12| ^Gene^Correlation^ |[[:human genes:h:hars|HARS]]|0.442| Global Fraction of Cell Lines Where Essential: 62/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|0/1| |bile duct|2/28| |blood|2/28| |bone|3/25| |breast|3/33| |central nervous system|6/56| |cervix|0/4| |colorectal|0/17| |esophagus|1/13| |fibroblast|0/1| |gastric|1/15| |kidney|4/21| |liver|1/20| |lung|5/75| |lymphocyte|2/14| |ovary|2/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|1/15| |prostate|0/1| |skin|3/24| |soft tissue|0/7| |thyroid|0/2| |upper aerodigestive|1/22| |urinary tract|5/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1273 * **Expression level (log2 read counts)**: 4.08 {{:chemogenomics:nalm6 dist.png?nolink |}}
