Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. {ECO:0000269|PubMed:15249124, ECO:0000269|PubMed:9660976}. |Med21| |DNA-directed 5-3 RNA polymerase activity| |mediator complex| |transcription coregulator activity| |blastocyst development| |ubiquitin ligase complex| |stem cell population maintenance| |maintenance of cell number| |ubiquitin protein ligase activity| |transcription coactivator activity| |in utero embryonic development| |chordate embryonic development| |embryo development ending in birth or egg hatching| |RNA biosynthetic process| |protein ubiquitination| |protein modification by small protein conjugation| |embryo development| |protein modification by small protein conjugation or removal| |nucleobase-containing compound biosynthetic process| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |positive regulation of transcription by RNA polymerase II| |organic cyclic compound biosynthetic process| |positive regulation of transcription, DNA-templated| |cellular nitrogen compound biosynthetic process| |positive regulation of nucleic acid-templated transcription| |positive regulation of RNA biosynthetic process| |RNA metabolic process| |positive regulation of RNA metabolic process| |macromolecule biosynthetic process| |positive regulation of nucleobase-containing compound metabolic process| |positive regulation of macromolecule biosynthetic process| |positive regulation of cellular biosynthetic process| |positive regulation of gene expression| |positive regulation of biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp450|Artemisinin 50μM R08 exp450]]|-2.05| |[[:results:exp449|Arsenic trioxide 60μM R08 exp449]]|-1.95| ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.508| Global Fraction of Cell Lines Where Essential: 40/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|5/28| |bone|1/25| |breast|6/33| |central nervous system|1/56| |cervix|1/4| |colorectal|3/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/15| |kidney|1/21| |liver|0/20| |lung|5/75| |lymphocyte|2/14| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|2/16| |plasma cell|2/15| |prostate|0/1| |skin|1/24| |soft tissue|0/7| |thyroid|0/2| |upper aerodigestive|1/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1670 * **Expression level (log2 read counts)**: 4.64 {{:chemogenomics:nalm6 dist.png?nolink |}}
