The stabilizing SNPs such as S1464I, A1705V and T1602I are found within the conserved and functional domains of NOTCH1. In addition, 1660\u20132555 sequence region of the PEST domain was recognized as an Intrinsically Disordered Region (IDR) with a score of above 0.5. Moreover, the presence of the two phosphodegrons (SCF_FBW7_1 at 2129\u20132136 and SCF_FBW7_2 at 2508\u20132515) along with the Post Translational Modification (PTM) such as o-linked glycosylation and Phosphothreonine within the IDR region, PEST and conserved domains suggest functional significance in LUAD progression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In conclusion our research highlights the potential regulatory role of identified SNPs, PTMs, and the functional domains of Notch1, particularly the PEST domain and IDR, in pathophysiology of LUAD particularly through the crosstalk of the EMT signalling.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fbinf.2025.1641521","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T06:40:58Z","timestamp":1765348858000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Neurogenic locus notch homolog protein 1 (NOTCH 1) SNP informatics coupled with intrinsically disordered regions and post-translational modifications reveals the complex structural crosstalk of Lung Adenocarcinoma (LUAD)"],"prefix":"10.3389","volume":"5","author":[{"given":"Pearl","family":"John","sequence":"first","affiliation":[]},{"given":"C.","family":"Sudandiradoss","sequence":"additional","affiliation":[]}],"member":"1965","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"722","DOI":"10.1038\/nrm.2016.94","article-title":"Notch signalling in context","volume":"17","author":"Bray","year":"2016","journal-title":"Nat.
