功能
C4 plays a central role in the activation of the classical pathway of the complement system. It is processed by activated C1 which removes from the alpha chain the C4a anaphylatoxin. The remaining alpha chain fragment C4b is the major activation product and is an essential subunit of the C3 convertase (C4b2a) and the C5 convertase (C3bC4b2a) enzymes of the classical complement pathway.
Derived from proteolytic degradation of complement C4, C4a anaphylatoxin is a mediator of local inflammatory process. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes. -
疾病相关
Defects in C4A are the cause of complement component 4A deficiency (C4AD) [MIM:120810]. A rare defect of the complement classical pathway associated with the development of autoimmune disorders, mainly systemic lupus with or without associated glomerulonephritis. -
序列相似性
Contains 1 anaphylatoxin-like domain.
Contains 1 NTR domain. -
翻译后修饰
Prior to secretion, the single-chain precursor is enzymatically cleaved to yield the non-identical chains (alpha, beta and gamma). During activation, the alpha chain is cleaved by C1 into C4a and C4b, and C4b stays linked to the beta and gamma chains. Further degradation of C4b by C1 into the inactive fragments C4c and C4d blocks the generation of C3 convertase.
N- and O-glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan. -

IHC image of C4d staining in human liver carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab87424, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Anti-C4d antibody (ab87424) at 1 µg/ml + Human Plasma Total Protein Lysate (ab83997) at 10 µg
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) (ab65484) at 1/3000 dilution (Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) )
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 193 kDa
Observed band size: 193,85 kDa why is the actual band size different from the predicted?
Additional bands at: 110 kDa, 130 kDa, 30 kDa, 48 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 seconds
C4d circulates in blood as a disulfide-linked trimer of an alpha, beta and gamma chain. Our immunogen sequence is within the alpha chain. The band at 85kDa could correspond to the alpha chain. -
ICC image of ab87424 stained HepG2 cells. The cells were 100% Methanol fixed (5 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab87424, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% Methanol fixed (5 min) HeLa, and MCF-7 cells at 5µg/ml.
