Activated C1 cleaves C2 into C2a and C2b. The serine proteinase C2a then combines with complement factor 4b to create the C3 or C5 convertase. Deficiency of C2 has been reported to associated with certain autoimmune diseases and SNPs in this gene have been associated with altered susceptibility to age-related macular degeneration. This gene localizes within the class III region of the MHC on the short arm of chromosome 6. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants have been described in publications but their full-length sequence has not been determined.[provided by RefSeq, Mar 2009]. * **<color #00a2e8>UniProt Summary</color>**: Component C2 which is part of the classical pathway of the complement system is cleaved by activated factor C1 into two fragments: C2b and C2a. C2a, a serine protease, then combines with complement factor C4b to generate the C3 or C5 convertase. <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'> |Sushi| |Trypsin| |VWA| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |positive regulation of apoptotic cell clearance| |regulation of apoptotic cell clearance| |positive regulation of phagocytosis| |regulation of phagocytosis| |regulation of complement activation| |regulation of humoral immune response| |complement activation, classical pathway| |serine-type endopeptidase activity| |humoral immune response mediated by circulating immunoglobulin| |complement activation| |immunoglobulin mediated immune response| |B cell mediated immunity| |response to nutrient| |lymphocyte mediated immunity| |adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains| |humoral immune response| |regulation of immune effector process| |response to nutrient levels| |response to extracellular stimulus| |regulation of vesicle-mediated transport| |adaptive immune response| |activation of immune response| |innate immune response| |leukocyte mediated immunity| |positive regulation of immune response| |defense response to other organism| |positive regulation of transport| |immune effector process| |regulation of immune response| |positive regulation of immune system process| |proteolysis| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |extracellular space| |regulation of immune system process| |regulation of transport| |immune response| |extracellular region| </modal> \\ === CRISPR Data === <button type='default' 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'> No hits were found. </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>**: 11715 * **<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='C2 Expression in NALM6 Cells: 3.42'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2026/01/07 22:36by 127.0.0.1
