Studies on the rat homolog implicate a role for this gene in autophagy, a process that involves the bulk degradation of cytoplasmic component. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Ubiquitin-like modifier involved in formation of autophagosomal vacuoles (autophagosomes). Plays a role in mitophagy which contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production. Whereas LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation. Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway. {ECO:0000269|PubMed:20418806, ECO:0000269|PubMed:23209295, ECO:0000269|PubMed:24089205}. |Atg8| |APG12| |organelle membrane| |cellular response to nitrogen levels| |cellular response to nitrogen starvation| |autophagosome membrane| |autophagosome maturation| |autophagy of mitochondrion| |mitochondrion disassembly| |autophagosome assembly| |organelle disassembly| |autophagosome organization| |autophagosome| |endomembrane system| |intracellular| |axoneme| |vacuole organization| |cellular response to starvation| |macroautophagy| |response to starvation| |cellular response to nutrient levels| |microtubule binding| |protein-containing complex disassembly| |cytoplasmic vesicle| |autophagy| |process utilizing autophagic mechanism| |cellular response to extracellular stimulus| |ubiquitin protein ligase binding| |microtubule| |cellular response to external stimulus| |cellular component disassembly| |mitochondrion organization| |response to nutrient levels| |response to extracellular stimulus| |organelle assembly| |mitochondrion| |cellular response to stress| |cellular catabolic process| |protein-containing complex subunit organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp247|UM0130462 0.025 to 0.035μM day4 R05 exp247]]|1.71| |[[:results:exp136|MS094 2μM R03 exp136]]|1.73| |[[:results:exp146|Quinacrine 2.5μM R03 exp146]]|1.82| |[[:results:exp129|Isonicotinamide 500μM R03 exp129]]|1.9| ^Gene^Correlation^ |[[:human genes:p:prim1|PRIM1]]|0.518| 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**: 3527 * **Expression level (log2 read counts)**: 5.61 {{:chemogenomics:nalm6 dist.png?nolink |}}
