InnateDB Gene IDBG-169700 (C8a)
Protein Structure
UniProt Annotation
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 (By similarity). {ECO:0000250}.
Subcellular Localization Secreted {ECO:0000250}. Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Note=Secreted as soluble protein. Inserts into the cell membrane of target cells (By similarity). {ECO:0000250}.
