Plays a critical role in protecting pancreatic beta-cells against oxidant stress, possibly by protecting the cell from excess buildup of reactive oxygen species (ROS). Reduces a variety of substrates in vitro, such as cytochrome c, feericyanide and methemoglobin. <button type='primary' size='sm' modal='Pfam_Domains'>Pfam Domains</button> <button type='primary' size='sm' modal='GO_terms'>GO Terms</button> <modal id='Pfam_Domains' size='lg' title='Pfam Domains'> |CS| |Cyt-b5| |FAD binding 6| |NAD binding 1| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |oxidoreductase activity, acting on NAD(P)H, heme protein as acceptor| |detection of oxygen| |cytochrome-b5 reductase activity, acting on NAD(P)H| |NAD(P)H oxidase activity| |insulin secretion| |superoxide metabolic process| |bicarbonate transport| |peptide hormone secretion| |hormone secretion| |hormone transport| |reactive oxygen species metabolic process| |heme binding| |protein secretion| |establishment of protein localization to extracellular region| |protein localization to extracellular region| |signal release| |peptide secretion| |glucose homeostasis| |carbohydrate homeostasis| |response to antibiotic| |response to oxygen levels| |generation of precursor metabolites and energy| |organic anion transport| |detection of chemical stimulus| |regulation of hormone levels| |anion transport| |detection of stimulus| |perinuclear region of cytoplasm| |endoplasmic reticulum membrane| |oxidation-reduction process| |secretion by cell| |endoplasmic reticulum| |export from cell| |chemical homeostasis| |cell-cell signaling| |secretion| |response to abiotic stimulus| |ion transport| |protein transport| |peptide transport| |amide transport| |establishment of protein localization| |homeostatic process| |cell development| |nitrogen compound transport| </modal> \\ === CRISPR Data === <button type='primary' size='small' modal='Compound_Hit'>Compound Hit</button> <button type='primary' size='small' modal='Most_Correlated_Genes'>Most Correlated Genes in Chemogenomics</button> <button type='primary' size='small' modal='Essential_Avana'>Tissues where Essential in the Avana Dataset (DepMap 20Q1)</button> <modal id='Compound_Hit' size='lg' title='Compound Hit'> ^Screen^Score^ |[[:results:exp432|YM155 0.001μM R08 exp432]]|-2.48| |[[:results:exp430|Rifampicin 30μM R08 exp430]]|-1.85| |[[:results:exp226|Cerivastatin 0.15μM R05 exp226]]|-1.78| |[[:results:exp38|Wortmannin 5μM R00 exp38]]|1.83| |[[:results:exp67|BVD-523 15μM R02 exp67]]|2| |[[:results:exp301|VER-155008 3.9μM R06 exp301]]|2.05| |[[:results:exp217|Mdivi-1 15μM R05 exp217]]|2.59| |[[:results:exp59|UMK57 1μM R01 exp59]]|2.83| |[[:results:exp502|Milciclib 2μM R08 exp502]]|3.49| |[[:results:exp80|RO-3307 4.7μM R02 exp80]]|3.82| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> ^Gene^Correlation^ |[[:human genes:p:ppp2r4|PPP2R4]]|0.584| |[[:human genes:t:tiprl|TIPRL]]|0.474| |[[:human genes:p:ppp6c|PPP6C]]|0.464| |[[:human genes:l:lcmt1|LCMT1]]|0.433| |[[:human genes:p:ppp6r3|PPP6R3]]|0.419| |[[:human genes:p:ppme1|PPME1]]|0.414| </modal> <modal id='Essential_Avana' size='lg' title='Tissues where Essential in the Avana Dataset (DepMap 20Q1)'> Global Fraction of Cell Lines Where Essential: 19/739 ^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|3/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|4/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|2/16| |plasma cell|0/15| |prostate|0/1| |skin|3/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|3/29| |uterus|0/5| </modal> == Essentiality in NALM6 == * **<color #00a2e8>Essentiality Rank</color>**: 4753 * **<color #00a2e8>Expression level (log2 read counts)</color>**: 5.9 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='CYB5R4 Expression in NALM6 Cells: 5.9'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2025/12/10 20:19by 127.0.0.1
