FTL Antibody / Ferritin light chain

The FTL gene encodes the light subunit of the ferritin protein. Ferritin is the major intracellular iron storage protein in prokaryotes and eukaryotes. It is composed of 24 subunits of the heavy and light ferritin chains. Variation in ferritin subunit composition may affect the rates of iron uptake and release in different tissues. A major function of ferritin is the storage of iron in a soluble and nontoxic state. This gene has multiple pseudogenes.

Although ferritin light chain has no ferroxidase activity, the light chain may be responsible for the electron transfer across the ferritin protein cage. [Wiki]
