Background: Serpin F1/PEDF

Serpin F1 (serine proteinase inhibitor-clade F #1; also PEDF, PIG35 and EPC-1) is a secreted, 50 kDa glycoprotein member of the clade F-subfamily, serpin superfamily of protease inhibitors.  It is expressed by diverse cell types such as retinal pigment and breast epithelium, fibroblasts, astrocytes and hepatocytes.  Serpin F1 circulates in blood and binds to type I collagen plus heparan sulfate.  Although it is a serpin, it belongs to a class of serpins that are nonprotease inhibiting, and instead is known to possess potent antiangiogenic and neurotrophic activity.  Human serpin F1 is 418 amino acids (aa) in length.  It contains a 19 aa signal sequence plus a 399 aa mature region that shows an NLS (aa 146-149), a neuroprotective motif (aa 354-359) and an antiangiogenesis segment (aa 387-411).  Phosphorylation occurs at multiple sites that affect bioactivity.  Over aa 44-418, human serpin F1 shares 87% aa identity with mouse serpin F1.
