MGI Phenotype FUNCTION: This gene encodes an inhibitor of both the classical and the alternative pathways of complement activation. This gene is located adjacent to a closely related gene on chromosome 1 and preferentially expressed in the spleen and testis. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Dec 2015]
