[[http://www.uniprot.org/uniprot/SODC_HUMAN SODC_HUMAN]] Defects in SOD1 are the cause of amyotrophic lateral sclerosis type 1 (ALS1) [MIM:[http://omim.org/entry/105400 105400]]. ALS1 is a familial form of amyotrophic lateral sclerosis, a neurodegenerative disorder affecting upper and lower motor neurons and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of cases leading to familial forms.<ref>PMID:12963370</ref><ref>PMID:19741096</ref><ref>PMID:8528216</ref><ref>PMID:8682505</ref><ref>PMID:9541385</ref><ref>PMID:12754496</ref><ref>PMID:15056757</ref><ref>PMID:18378676</ref>[:]<ref>PMID:8446170</ref><ref>PMID:8351519</ref><ref>PMID:8179602</ref><ref>PMID:7980516</ref><ref>PMID:8069312</ref><ref>PMID:7951252</ref><ref>PMID:7881433</ref><ref>PMID:7836951</ref><ref>PMID:7997024</ref><ref>PMID:7870076</ref><ref>PMID:7887412</ref><ref>PMID:7795609</ref><ref>PMID:7655468</ref><ref>PMID:7655469</ref><ref>PMID:7655471</ref><ref>PMID:7700376</ref><ref>PMID:7647793</ref><ref>PMID:7501156</ref><ref>PMID:7496169</ref><ref>PMID:8938700</ref><ref>PMID:8907321</ref><ref>PMID:8990014</ref><ref>PMID:9101297</ref><ref>PMID:9455977</ref><ref>PMID:10732812</ref><ref>PMID:9131652</ref><ref>PMID:10400992</ref><ref>PMID:10430435</ref><ref>PMID:11535232</ref><ref>PMID:11369193</ref><ref>PMID:12402272</ref><ref>PMID:12145308</ref><ref>PMID:14506936</ref><ref>PMID:18552350</ref><ref>PMID:18301754</ref><ref>PMID:21247266</ref><ref>PMID:21220647</ref>

== Publication Abstract from PubMed ==
 +
SOD1 has to undergo several post-translational modifications before reaching its mature form. The protein requires insertion of zinc and copper atoms, followed by the formation of a conserved S-S bond between Cys-57 and Cys-146 (human numbering), which makes the protein fully active. In this report an NMR structural investigation of the reduced SH-SH form of thermostable E,Zn-as-SOD1 (E is empty; as is C6A, C111S) is reported, characterizing the protein just before the last step leading to the mature form. The structure is compared with that of the oxidized S-S form as well as with that of the yeast SOD1 complexed with its copper chaperone, CCS. Local conformational rearrangements upon disulfide bridge reduction are localized in the region near Cys-57 that is completely exposed to the solvent in the present structure, at variance with the oxidized forms. There is a local disorder around Cys-57 that may serve for protein-protein recognition and may possibly be involved in intermolecular S-S bonds in familial amyotrophic lateral sclerosis-related SOD1 mutants. The structure allows us to further discuss the copper loading mechanism in SOD1.
