The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference, complexes with this subunit showing a clear preference for longer acyl-CoAs. The SPTLC1-SPTLC2-SPTSSB complex shows a strong preference for C18-CoA substrate, while the SPTLC1-SPTLC3-SPTSSB isozyme displays an ability to use a broader range of acyl-CoAs, without apparent preference. May play a role in signal transduction. {ECO:0000269|PubMed:19416851}. <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'> |DUF3317| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |regulation of serine C-palmitoyltransferase activity| |serine C-palmitoyltransferase activity| |serine C-palmitoyltransferase complex| |ceramide biosynthetic process| |endoplasmic reticulum organization| |ceramide metabolic process| |sphingolipid biosynthetic process| |membrane lipid biosynthetic process| |sphingolipid metabolic process| |membrane lipid metabolic process| |endomembrane system organization| |amide biosynthetic process| |lipid biosynthetic process| |cellular amide metabolic process| |endoplasmic reticulum membrane| |cellular lipid metabolic process| |regulation of transferase activity| |lipid metabolic process| |organonitrogen compound biosynthetic process| |cellular nitrogen compound biosynthetic process| </modal> \\ === CRISPR Data === <button type='primary' size='small' modal='Compound_Hit'>Compound Hit</button> <button type='default' 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:exp519|RS-1 10μM R08 exp519]]|-1.75| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> No correlation found to any other genes in chemogenomics. </modal> <modal id='Essential_Avana' size='lg' title='Tissues where Essential in the Avana Dataset (DepMap 20Q1)'> 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| </modal> == Essentiality in NALM6 == * **<color #00a2e8>Essentiality Rank</color>**: 16666 * **<color #00a2e8>Expression level (log2 read counts)</color>**: -7.68 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='SPTSSB Expression in NALM6 Cells: -7.68'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2026/01/07 22:37by 127.0.0.1
