  • 靶标

    • 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.

    • Predicted band size : 193 kDa
      Observed band size : 41,200 kDa (why is the actual band size different from the predicted?)

      Western blot analysis using ab89537. Serum from a C57BL6 mouse was aged for 0, 1 and 4 days at 37degrees C to allow cleavage of C4 to C4d. Blots reacted with ab89537 yielded both a 200 kDa band as well as a 41 kDa band corresponding to the molecular weight of C4d.


    ab89537 has not yet been referenced specifically in any publications.


    Thank you for contacting us. I have been doing a little research into C4 and the antibodies that we currently have available against this target. As discussed on the phone, ab89537 recognises mouse C4d and C4 and has been tested in flow cytomet...
