We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Frataxin often known by the alternate name FXN is a mitochondrial protein with a mass of approximately 21000 Dalton. It is expressed mainly in tissues with high energy demands like the heart liver and pancreas. Frataxin plays an important role in iron-sulfur cluster assembly which is essential for various cellular processes. The protein is a part of mitochondria where it regulates iron homeostasis and prevents oxidative damage by minimizing iron-induced free radical generation.

Biological function summary

Several cellular processes depend on the correct function of this protein. Frataxin assists in forming iron-sulfur clusters acting within a multiprotein complex in the mitochondria. The complex includes proteins such as ISCU which are involved in the assembly and repair of iron-sulfur clusters. These clusters are necessary for supporting mitochondrial electron transport and other fundamental metabolic pathways that require iron-sulfur dependencies.

Pathways

Frataxin's involvement extensively affects the mitochondrial respiratory chain and the mitochondrial biogenesis process. It plays a role in the electron transport chain by stabilizing iron-sulfur-containing complexes. NAB is one associated protein that interacts closely within these pathways sharing a connection through iron-sulfur cluster transportation and assembly systems. Efficient function of these pathways ensures a proper energetic output of cells.

Frataxin mutations are directly linked to Friedreich's ataxia a neurodegenerative disease causing progressive damage to the nervous system. The deficiency or dysfunction in frataxin causes accumulation of iron in mitochondria leading to increased oxidative stress. Another related disorder includes heart disease which emerges due to the same oxidative stress pathway. Proteins such as Nfs1 are also involved sharing the responsibility with frataxin in scavenging excess iron protecting against related tissue damage.

Target data

Frataxin mature form. Functions as an activator of persulfide transfer to the scaffoding protein ISCU as component of the core iron-sulfur cluster (ISC) assembly complex and participates to the [2Fe-2S] cluster assembly (PubMed : 12785837, PubMed : 24971490). Accelerates sulfur transfer from NFS1 persulfide intermediate to ISCU and to small thiols such as L-cysteine and glutathione leading to persulfuration of these thiols and ultimately sulfide release (PubMed : 24971490). Binds ferrous ion and is released from FXN upon the addition of both L-cysteine and reduced FDX2 during [2Fe-2S] cluster assembly (PubMed : 29576242). The core iron-sulfur cluster (ISC) assembly complex is involved in the de novo synthesis of a [2Fe-2S] cluster, the first step of the mitochondrial iron-sulfur protein biogenesis. This process is initiated by the cysteine desulfurase complex (NFS1 : LYRM4 : NDUFAB1) that produces persulfide which is delivered on the scaffold protein ISCU in a FXN-dependent manner. Then this complex is stabilized by FDX2 which provides reducing equivalents to accomplish the [2Fe-2S] cluster assembly. Finally, the [2Fe-2S] cluster is transferred from ISCU to chaperone proteins, including HSCB, HSPA9 and GLRX5 (By similarity). May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+); the oligomeric form but not the monomeric form has in vitro ferroxidase activity (PubMed : 15641778). May be able to store large amounts of iron in the form of a ferrihydrite mineral by oligomerization; however, the physiological relevance is unsure as reports are conflicting and the function has only been shown using heterologous overexpression systems (PubMed : 11823441, PubMed : 12755598). May function as an iron chaperone protein that protects the aconitase [4Fe-4S]2+ cluster from disassembly and promotes enzyme reactivation (PubMed : 15247478). May play a role as a high affinity iron binding partner for FECH that is capable of both delivering iron to ferrochelatase and mediating the terminal step in mitochondrial heme biosynthesis (PubMed : 15123683, PubMed : 16239244).. Extramitochondrial frataxin. Modulates the RNA-binding activity of ACO1 (PubMed : 20053667). May be involved in the cytoplasmic iron-sulfur protein biogenesis (PubMed : 16091420). May contribute to oxidative stress resistance and overall cell survival (PubMed : 16608849).
