Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [43] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [44] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [40]
PANK2 encodes a 1.85Kb transcript which is derived from seven exons covering a total distance of approximately 3.5Mb of genomic DNA. The PANK2 gene also encodes a 50.5-kDa protein that is a functional pantothenate kinase , an essential regulatory enzyme in coenzyme A (CoA) biosynthesis, and catalyzing the phosphorylation of pantothenate ...
Iron is also the most abundant transition metal in the human body and it is used in various processes like oxygen transport and ATP production. It plays a key role in the function of enzymes like cytochrome a , b and c as well as iron-sulfur complexes which play an important role in ATP production. [ 13 ]
Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [28] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [29] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [25]
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.

Transferrin saturation (TS), measured as a percentage, is a medical laboratory value. It is the value of serum iron divided by the total iron-binding capacity [1] of the available transferrin, the main protein that binds iron in the blood, this value tells a clinician how much serum iron is bound.
In molecular biology, the iron response element or iron-responsive element (IRE) is a short conserved stem-loop which is bound by iron response proteins (IRPs, also named IRE-BP or IRBP). The IRE is found in UTRs (untranslated regions) of various mRNAs whose products are involved in iron metabolism .
