[https://www.uniprot.org/uniprot/SODC_HUMAN SODC_HUMAN] Defects in SOD1 are the cause of amyotrophic lateral sclerosis type 1 (ALS1) [MIM:[https://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 ==
 +
The gain of neurotoxic function in amyotrophic lateral sclerosis (ALS) has been linked to misfolding of the homodimeric enzyme Cu/Zn superoxide dismutase (SOD). Here, we present the crystal structure of fully cysteine-depleted human SOD (SOD(CallA)), representing a reduced, marginally stable intermediate on the folding pathway in vivo that has also been implicated as neurotoxic precursor state. A hallmark of this species is that it fails to dimerize and becomes trapped as a monomer in the absence of the active-site metals. The crystallographic data show that removal of the C57-C146 disulphide bond sets free the interface loop IV in the apo protein, whereas the same loop remains unaffected in the holo protein. Thus, the low dimerisation propensity of disulphide-reduced apoSOD seems to be of entropic origin due to increased loop flexibility in the monomeric state: in the disulphide-reduced holo protein this gain in configurational entropy upon splitting of the dimer interface is reduced by the metal coordination.
