This gene encodes a member of the S1, or chymotrypsin, family of serine peptidases. This protease catalyzes the cleavage of factor B, the rate-limiting step of the alternative pathway of complement activation. This protein also functions as an adipokine, a cell signaling protein secreted by adipocytes, which regulates insulin secretion in mice. Mutations in this gene underlie complement factor D deficiency, which is associated with recurrent bacterial meningitis infections in human patients. Alternative splicing of this gene results in multiple transcript variants. At least one of these variants encodes a preproprotein that is proteolytically processed to generate the mature protease.

A study in pigs demonstrated that the CFD gene was downregulated in subcutaneous fat tissue from the center of experimental bruises over time (2, 5, and 8 hours post-infliction) relative to uninjured control tissue [Barington et al. DOI:10.1016/J.Jflm.2018.06.005].
