Responsible for the E2-like covalent binding of phosphatidylethanolamine to the C-terminal Gly of ATG8-like proteins (GABARAP, GABARAPL1, GABARAPL2 or MAP1LC3A). The ATG12- ATG5 conjugate plays a role of an E3 and promotes the transfer of ATG8-like proteins from ATG3 to phosphatidylethanolamine (PE). This step is required for the membrane association of ATG8-like proteins. The formation of the ATG8-phosphatidylethanolamine conjugates is essential for autophagy and for the cytoplasm to vacuole transport (Cvt). Preferred substrate is MAP1LC3A. Also acts as an autocatalytic E2-like enzyme, catalyzing the conjugation of ATG12 to itself, ATG12 conjugation to ATG3 playing a role in mitochondrial homeostasis but not in autophagy. ATG7 (E1-like enzyme) facilitates this reaction by forming an E1-E2 complex with ATG3. Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway. {ECO:0000269|PubMed:11825910, ECO:0000269|PubMed:12207896, ECO:0000269|PubMed:12890687, ECO:0000269|PubMed:16704426, ECO:0000269|PubMed:20723759}. |Autophagy Cterm| |Autophagy act C| |Autophagy N| |cytoplasmic ubiquitin ligase complex| |Atg12 transferase activity| |Atg8 ligase activity| |ubiquitin-like protein transferase activity| |mitochondrial fragmentation involved in apoptotic process| |negative regulation of phagocytosis| |mitochondrion disassembly| |autophagy of mitochondrion| |apoptotic mitochondrial changes| |autophagosome assembly| |organelle disassembly| |autophagosome organization| |regulation of cilium assembly| |regulation of phagocytosis| |vacuole organization| |protein targeting to membrane| |macroautophagy| |regulation of plasma membrane bounded cell projection assembly| |regulation of cell projection assembly| |regulation of organelle assembly| |autophagy| |process utilizing autophagic mechanism| |establishment of protein localization to membrane| |enzyme binding| |protein targeting| |cellular component disassembly| |mitochondrion organization| |protein localization to membrane| |negative regulation of transport| |regulation of vesicle-mediated transport| |protein ubiquitination| |regulation of plasma membrane bounded cell projection organization| |regulation of cell projection organization| |organelle assembly| |protein modification by small protein conjugation| |apoptotic process| |regulation of cellular component biogenesis| |protein modification by small protein conjugation or removal| |intracellular protein transport| |programmed cell death| |cell death| |regulation of organelle organization| |protein transport| |intracellular transport| |peptide transport| |amide transport| |cellular protein localization| |cellular macromolecule localization| |establishment of protein localization| |cellular catabolic process| |establishment of localization in cell| |nitrogen compound transport| |regulation of transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp320|ABT-702 5μM plus CoCl2 18μM R07 exp320]]|-2.02| |[[:results:exp10|CCCP 0.1μM R00 exp10]]|-1.81| |[[:results:exp32|Rifampicin 10μM R00 exp32]]|1.8| |[[:results:exp51|Nifuroxazide 1μM R01 exp51]]|1.81| |[[:results:exp211|AICAR 240μM R05 exp211]]|1.82| |[[:results:exp469|CFI-400945 25μM R08 exp469]]|1.87| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.553| 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**: 11214 * **Expression level (log2 read counts)**: 5.96 {{:chemogenomics:nalm6 dist.png?nolink |}}
