The first step is the transfer of a sulfate group to ATP to yield adenosine 5'-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3'-phosphoadenylylsulfate (PAPS: activated sulfate donor used by sulfotransferase). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate- activation pathway (PubMed:9576487, PubMed:9668121, PubMed:9648242, PubMed:14747722). Required for normal biosynthesis of sulfated L-selectin ligands in endothelial cells (PubMed:9576487). {ECO:0000269|PubMed:14747722, ECO:0000269|PubMed:9576487, ECO:0000269|PubMed:9648242, ECO:0000269|PubMed:9668121}. |ATP-sulfurylase| |APS kinase| |adenylylsulfate kinase activity| |sulfate adenylyltransferase (ATP) activity| |sulfate assimilation| |purine ribonucleoside bisphosphate biosynthetic process| |3-phosphoadenosine 5-phosphosulfate biosynthetic process| |nucleotidyltransferase activity| |3-phosphoadenosine 5-phosphosulfate metabolic process| |purine ribonucleoside bisphosphate metabolic process| |ribonucleoside bisphosphate biosynthetic process| |nucleoside bisphosphate biosynthetic process| |purine nucleoside bisphosphate biosynthetic process| |purine nucleoside bisphosphate metabolic process| |nucleoside bisphosphate metabolic process| |ribonucleoside bisphosphate metabolic process| |purine ribonucleotide biosynthetic process| |purine nucleotide biosynthetic process| |ribonucleotide biosynthetic process| |ribose phosphate biosynthetic process| |purine-containing compound biosynthetic process| |sulfur compound biosynthetic process| |nucleotide biosynthetic process| |nucleoside phosphate biosynthetic process| |purine ribonucleotide metabolic process| |ribonucleotide metabolic process| |purine nucleotide metabolic process| |ribose phosphate metabolic process| |sulfur compound metabolic process| |purine-containing compound metabolic process| |nucleotide metabolic process| |nucleoside phosphate metabolic process| |skeletal system development| |organophosphate biosynthetic process| |nucleobase-containing small molecule metabolic process| |carbohydrate derivative biosynthetic process| |protein homodimerization activity| |organophosphate metabolic process| |oxoacid metabolic process| |organic acid metabolic process| |carbohydrate derivative metabolic process| |nucleobase-containing compound biosynthetic process| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |phosphorylation| |organic cyclic compound biosynthetic process| |organonitrogen compound biosynthetic process| |ATP binding| |cellular nitrogen compound biosynthetic process| |small molecule metabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp472|CI-1040 9.5μM R08 exp472]]|-2.08| |[[:results:exp329|Hydroxyurea 100μM R07 exp329]]|-1.87| |[[:results:exp149|SB203580 25μM R03 exp149]]|2.04| |[[:results:exp406|Thalidomide 20μM R07 exp406]]|2.19| |[[:results:exp301|VER-155008 3.9μM R06 exp301]]|2.38| |[[:results:exp240|Pyridostatin 4μM R05 exp240]]|2.94| ^Gene^Correlation^ |[[:human genes:u:ugdh|UGDH]]|0.45| |[[:human genes:f:fam20b|FAM20B]]|0.447| |[[:human genes:b:b3gat3|B3GAT3]]|0.426| Global Fraction of Cell Lines Where Essential: 1/739 ^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|1/15| |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**: 5264 * **Expression level (log2 read counts)**: 5.12 {{:chemogenomics:nalm6 dist.png?nolink |}}
