Function
C1s B chain is a serine protease that combines with C1q and C1s to form C1, the first component of the classical pathway of the complement system. C1r activates C1s so that it can, in turn, activate C2 and C4. -
Involvement in disease
Defects in C1S are the cause of complement component C1s deficiency (C1SD) [MIM:613783]. A rare defect resulting in C1 deficiency and impaired activation of the complement classical pathway. C1 deficiency generally leads to severe immune complex disease with features of systemic lupus erythematosus and glomerulonephritis. -
Sequence similarities
Belongs to the peptidase S1 family.
Contains 2 CUB domains.
Contains 1 EGF-like domain.
Contains 1 peptidase S1 domain.
Contains 2 Sushi (CCP/SCR) domains. -
Post-translational
modificationsThe iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains. - Information by UniProt

Western blot - Anti-C1s antibody (ab87986)Anti-C1s antibody (ab87986) at 1 µg/ml + Human Plasma Total Protein Lysate at 10 µg
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 76 kDa
Observed band size: 88 kDa why is the actual band size different from the predicted?
Exposure time: 3 minutes
The Complement C1s subcomponent protein contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
