The receptors for the different products of dermcidin remain largely uncharacterised, although both high- and low-affinity receptors on breast cancer cells bind dermcidin with alkaline phospatase attached to the DCD-1 carboxy-terminus (Porter et al, 2003) and glycosylated PIF has been suggested to bind to both hepatocytes and skeletal muscle (Waddell et al, unpublished observation). The gene discussed is DCD; the disease is breast cancer.
