In the most common inherited dementia, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), mutations in NOTCH3 that alter extracellular cysteine number have implicated NOTCH3 cysteine states as potential triggers of cerebral vascular smooth muscle cytopathology. In this report, we describe a novel property of the second EGF-like domain of NOTCH3: its capacity to alter the cysteine redox state of the NOTCH3 ectodomain. Synthetic peptides corresponding to this sequence (NOTCH3 N-terminal fragment 2, NTF2) readily reduce NOTCH3 N-terminal ectodomain polypeptides in a dose- and time-dependent fashion. Furthermore, NTF2 preferentially reduces regional domains of NOTCH3 with the highest intensity against EGF-like domains 12\u201315. This process requires cysteine residues of NTF2 and is also capable of targeting selected extracellular proteins that include TSP2 and CTSH. CADASIL mutations in NOTCH3 increase susceptibility to NTF2-facilitated reduction and to trans-reduction by NOTCH3 produced in cells. Moreover, NTF2 forms complexes with the NOTCH3 ectodomain, and cleaved NOTCH3 co-localizes with the NOTCH3 ectodomain in cerebral arteries of CADASIL patients. The potential for NTF2 to reduce vascular proteins and the enhanced preference for it to trans-reduce mutant NOTCH3 implicate a role for protein trans-reduction in cerebrovascular pathological states such as CADASIL.<\/jats:p>","DOI":"10.3390\/ijms23073671","type":"journal-article","created":{"date-parts":[[2022,3,27]],"date-time":"2022-03-27T21:27:51Z","timestamp":1648416471000},"page":"3671","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Trans-Reduction of Cerebral Small Vessel Disease Proteins by Notch-Derived EGF-like Sequences"],"prefix":"10.3390","volume":"23","author":[{"given":"Naw May Pearl","family":"Cartee","sequence":"first","affiliation":[{"name":"Department of Neurology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Neurology Service, VA Ann Arbor Healthcare System, Ann Arbor, MI 48105, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soo Jung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Neurology Service, VA Ann Arbor Healthcare System, Ann Arbor, MI 48105, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelly Z.","family":"Young","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Neurology Service, VA Ann Arbor Healthcare System, Ann Arbor, MI 48105, USA"},{"name":"Department of Molecular & Integrative Physiology, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaojie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Neurology Service, VA Ann Arbor Healthcare System, Ann Arbor, MI 48105, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5670-2496","authenticated-orcid":false,"given":"Michael M.","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Neurology Service, VA Ann Arbor Healthcare System, Ann Arbor, MI 48105, USA"},{"name":"Department of Molecular & Integrative Physiology, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1002\/mas.21430","article-title":"ROSics: Chemistry and proteomics of cysteine modifications in redox biology","volume":"34","author":"Kim","year":"2015","journal-title":"Mass Spectrom.
