Structural highlights
FunctionFRIL_HORSE Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity). Publication Abstract from PubMedProtein cages have been utilized as templates in the development of biomaterials. Here we report protein engineering of the ferritin (Fr) cage for encapsulating carbon monoxide releasing molecules (CORMs) and release of CO gas which serves as a cell signaling molecule. The protein cages enable us to increase the half-life for CO release, providing a release rate that is 18-fold slower than the rate of a typical CORM, Ru(CO)3Cl(glycinate) (CORM-3). Moreover, the uptake ratio of the composite is about 4-fold greater than that of CORM-3. We found that these effects enhance the activation of nuclear factor kappaB 10-fold higher than CORM-3. The protein cage of Fr thus provides the basis for new CORMs that can be used for in vitro cell research.
