The encoded protein is involved in multiubiquitin chain assembly and plays a critical role in chromosome condensation and separation through the polyubiquitination of securin. Autoantibodies against the encoded protein may be markers for scleroderma and Crohn's disease. A pseudogene of this gene is located on the long arm of chromosome 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2011]. * **UniProt Summary**: Ubiquitin-protein ligase that probably functions as an E3 ligase in conjunction with specific E1 and E2 ligases. May also function as an E4 ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. Mediates 'Lys-48'-linked polyubiquitination of substrates. {ECO:0000250|UniProtKB:E9Q735, ECO:0000250|UniProtKB:P54860}. |Ufd2P core| |U-box| |ubiquitin-ubiquitin ligase activity| |ubiquitin-dependent ERAD pathway| |ERAD pathway| |ubiquitin ligase complex| |response to endoplasmic reticulum stress| |protein polyubiquitination| |proteasome-mediated ubiquitin-dependent protein catabolic process| |proteasomal protein catabolic process| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular protein catabolic process| |protein catabolic process| |protein ubiquitination| |protein modification by small protein conjugation| |cellular macromolecule catabolic process| |protein modification by small protein conjugation or removal| |response to organonitrogen compound| |macromolecule catabolic process| |organonitrogen compound catabolic process| |response to nitrogen compound| |proteolysis| |cellular response to stress| |organic substance catabolic process| |cellular catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp19|Etoposide 1μM R00 exp19]]|-2.93| |[[:results:exp355|Dinaciclib 0.007μM R07 exp355]]|-2.19| |[[:results:exp539|42°C R08 exp539]]|-2.13| |[[:results:exp64|Nocodazole 0.2μM R02 exp64]]|-2.12| |[[:results:exp80|RO-3307 4.7μM R02 exp80]]|-2.07| |[[:results:exp529|Thimerosal 0.85μM R08 exp529]]|-1.99| |[[:results:exp199|Etoposide 0.3μM R05 exp199]]|-1.93| |[[:results:exp459|Bleomycin 5μM R08 exp459]]|-1.9| |[[:results:exp264|Arsenate 40μM R06 exp264]]|-1.89| |[[:results:exp527|Tanespimycin 14μM R08 exp527]]|-1.89| |[[:results:exp72|LB-100 4.1μM R02 exp72]]|-1.77| |[[:results:exp34|Rotenone 20μM R00 exp34]]|-1.76| |[[:results:exp506|Momordin-Ic 10μM R08 exp506]]|2.08| |[[:results:exp6|Bortezomib 0.005μM R00 exp6]]|2.88| ^Gene^Correlation^ |[[:human genes:p:polr2j3|POLR2J3]]|0.429| |[[:human genes:m:mtch2|MTCH2]]|0.427| |[[:human genes:z:zfand5|ZFAND5]]|0.415| |[[:human genes:u:ubxn4|UBXN4]]|0.4| 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**: 10746 * **Expression level (log2 read counts)**: 7.33 {{:chemogenomics:nalm6 dist.png?nolink |}}
