应用 Ab评论 说明
WB Use a concentration of 2 µg/ml. Detects a band of approximately 95 kDa (predicted molecular weight: 193 kDa).

Complement C4-A circulates in blood as a disulphide linked trimer of an alpha, beta and gamma chain (95, 75 and 33 kDa respectively). Our immunogen sequence is within the region corresponding to the alpha chain (95 kDa).

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.
