Protein name:
Complement component C8 alpha chain ;
Alternative:
Complement component 8 subunit alpha ;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
Heterotrimer of 3 chains: alpha, beta and gamma. The alpha and gamma chains are disulfide bonded. Component of the membrane attack complex (MAC). MAC assembly is initiated by protelytic cleavage of C5 into C5a and C5b. C5b binds sequentially C6, C7, C8 and multiple copies of the pore-forming subunit C9.
Function:
Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells. C8A inserts into the target membrane, but does not form pores by itself.
Subcellular Location:
Secreted
Cell membrane
Multi-pass membrane protein
Secreted as soluble protein. Inserts into the cell membrane of target cells.
