PIF, proteolysis-inducing factor, PIF1, Dermcidin
This gene encodes a secreted protein that is subsequently processed into mature peptides of distinct biological activities. The C-terminal peptide is constitutively expressed in sweat and has antibacterial and antifungal activities. The N-terminal peptide, also known as diffusible survival evasion peptide, promotes neural cell survival under conditions of severe oxidative stress. A glycosylated form of the N-terminal peptide may be associated with cachexia (muscle wasting) in cancer patients. [provided by RefSeq, Jul 2008] (from NCBI)

Papers on PIF
Cryptochromes Interact Directly with PIFs to Control Plant Growth in Limiting Blue Light.
