C1q is composed of 18 polypeptide chains which include 6 A-chains, 6 B-chains, and 6 C-chains. Each chain contains an N-terminal collagen-like region and a C-terminal C1q globular domain. C1q deficiency is associated with lupus erythematosus and glomerulonephritis. [provided by RefSeq, Dec 2016]. * **<color #00a2e8>UniProt Summary</color>**: C1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system. The collagen-like regions of C1q interact with the Ca(2+)-dependent C1r(2)C1s(2) proenzyme complex, and efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or IgM antibody present in immune complexes. <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'> |Collagen| |C1q| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |negative regulation of macrophage differentiation| |negative regulation of granulocyte differentiation| |synapse pruning| |regulation of granulocyte differentiation| |regulation of macrophage differentiation| |negative regulation of myeloid leukocyte differentiation| |collagen trimer| |negative regulation of myeloid cell differentiation| |cell| |postsynapse| |negative regulation of leukocyte differentiation| |regulation of myeloid leukocyte differentiation| |regulation of complement activation| |regulation of humoral immune response| |negative regulation of hemopoiesis| |blood microparticle| |complement activation, classical pathway| |humoral immune response mediated by circulating immunoglobulin| |complement activation| |immunoglobulin mediated immune response| |B cell mediated immunity| |regulation of myeloid cell differentiation| |lymphocyte mediated immunity| |synapse| |synapse organization| |regulation of leukocyte differentiation| |adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains| |humoral immune response| |collagen-containing extracellular matrix| |cellular component disassembly| |negative regulation of immune system process| |regulation of hemopoiesis| |regulation of immune effector process| |adaptive immune response| |activation of immune response| |negative regulation of cell differentiation| |innate immune response| |leukocyte mediated immunity| |positive regulation of immune response| |negative regulation of developmental process| |defense response to other organism| |immune effector process| |regulation of immune response| |positive regulation of immune system process| |negative regulation of multicellular organismal process| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |extracellular space| |regulation of immune system process| |regulation of cell differentiation| |immune response| |extracellular region| </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:exp38|Wortmannin 5μM R00 exp38]]|-1.93| |[[:results:exp28|Pimelic-diphenylamide-106 5μM R00 exp28]]|-1.82| |[[:results:exp450|Artemisinin 50μM R08 exp450]]|1.75| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.486| </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>**: 10802 * **<color #00a2e8>Expression level (log2 read counts)</color>**: -3.42 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='C1QC Expression in NALM6 Cells: -3.42'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2025/12/10 20:19by 127.0.0.1
