== Disease ==
[https://www.uniprot.org/uniprot/DNM1L_HUMAN DNM1L_HUMAN] Note=May be associated with Alzheimer disease through beta-amyloid-induced increased S-nitrosylation of DNM1L, which triggers, directly or indirectly, excessive mitochondrial fission, synaptic loss and neuronal damage.<ref>PMID:19342591</ref>   Defects in DNM1L are the cause of encephalopathy, lethal, due to defective mitochondrial and peroxisomal fission (EMPF) [MIM:[https://omim.org/entry/614388 614388]. EMPF is a rare autosomal dominant systemic disorder resulting in lack of neurologic development and death in infancy. After birth, infants present in the first week of life with poor feeding and neurologic impairment, including hypotonia, little spontaneous movement, no tendon reflexes, no response to light stimulation, and poor visual fixation. Other features include mildly elevated plasma concentration of very-long-chain fatty acids, lactic acidosis, microcephaly, deep-set eyes, optic atrophy and hypoplasia, and an abnormal gyral pattern in both frontal lobes associated with dysmyelination.<ref>PMID:17460227</ref> <ref>PMID:19342591</ref> 
== Function ==
[https://www.uniprot.org/uniprot/DNM1L_HUMAN DNM1L_HUMAN] Functions in mitochondrial and peroxisomal division. Mediates membrane fission through oligomerization into ring-like structures which wrap around the scission site to constict and sever the mitochondrial membrane through a GTP hydrolysis-dependent mechanism. Required for normal brain development. Facilitates developmentally-regulated apoptosis during neural tube development. Required for a normal rate of cytochrome c release and caspase activation during apoptosis. Also required for mitochondrial fission during mitosis. Required for programmed necrosis execution. May be involved in vesicle transport.<ref>PMID:9570752</ref> <ref>PMID:9786947</ref> <ref>PMID:11514614</ref> <ref>PMID:12499366</ref> <ref>PMID:12618434</ref> <ref>PMID:15208300</ref> <ref>PMID:17015472</ref> <ref>PMID:17301055</ref> <ref>PMID:17553808</ref> <ref>PMID:17460227</ref> <ref>PMID:18695047</ref> <ref>PMID:18838687</ref> <ref>PMID:19638400</ref> <ref>PMID:19411255</ref> <ref>PMID:19342591</ref> <ref>PMID:20688057</ref>   Isoform 1 and isoform 4 inhibit peroxisomal division when overexpressed.<ref>PMID:9570752</ref> <ref>PMID:9786947</ref> <ref>PMID:11514614</ref> <ref>PMID:12499366</ref> <ref>PMID:12618434</ref> <ref>PMID:15208300</ref> <ref>PMID:17015472</ref> <ref>PMID:17301055</ref> <ref>PMID:17553808</ref> <ref>PMID:17460227</ref> <ref>PMID:18695047</ref> <ref>PMID:18838687</ref> <ref>PMID:19638400</ref> <ref>PMID:19411255</ref> <ref>PMID:19342591</ref> <ref>PMID:20688057</ref>
