GENE AND PROTEIN SUMMARY

? »

Gene name

C9

Description

complement component 9

Protein class

Mapped to UniProt SWISS-PROT, Plasma proteins, Potential transmembrane proteins, Potentially secreted proteins

Protein evidence

High

Entrez gene 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. Mutations in this gene cause component C9 deficiency.
