Gene Gene information from NCBI Gene database.
Entrez ID 735
Gene name Complement C9
Gene symbol C9
Synonyms (NCBI Gene)
ARMD15C9D
Chromosome 5
Chromosome location 5p13.1
Summary This gene encodes the final component of the complement system. It participates in the formation of the Membrane Attack Complex (MAC). The MAC assembles on bacterial membranes to form a pore, permitting disruption of bacterial membrane organization. Mutat
