Gene Gene information from NCBI Gene database.
Entrez ID 715
Gene name Complement C1r
Gene symbol C1R
Synonyms (NCBI Gene)
EDS8EDSPD1
Chromosome 12
Chromosome location 12p13.31
Summary This gene encodes a member of the peptidase S1 protein family. The encoded protein is a proteolytic subunit in the complement system C1 complex. The complement system acts as a mediator in the innate immune response by ultimately triggering phagocytosis,
