However, existing computational methods primarily focus on binary pathogenicity classification for general proteins, with limited approaches specifically designed for membrane proteins, and even fewer methods capable of fine-grained, multi-label classification for specific disease categories. To address this gap, we proposed MutDPAL, a deep learning method specifically designed to identify pathogenic mutations in membrane proteins and further classify such pathogenic mutations into potential diseases categories. MutDPAL utilizes two pre-trained biological large language models (Bio-LLMs), one for raw sequence features and the other for encoding transmembrane environment features. By employing a cross-attention-based disease-protein association learning approach in the context of membrane proteins, MutDPAL captures the intricate relationships between mutations and diseases, enabling accurate pathogenicity prediction and classification into 15 distinct disease categories. Experimental results demonstrate that MutDPAL outperforms existing methods in predicting membrane protein mutation pathogenicity and excels in multi-label disease classification tasks, achieving high predictive accuracy across all 15 disease categories. MutDPAL is the first to combine transmembrane environment with disease encoding features for fine-grained disease classification, offering valuable insights into the pathogenicity of missense mutations in membrane protein.</p>","PeriodicalId":10552,"journal":{"name":"Communications Biology","volume":"8 1","pages":"1050"},"PeriodicalIF":5.2,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12264167/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144642022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This instability arises from defects in critical cellular processes, particularly those involved in DNA damage repair. Therefore, a detailed understanding of these repair mechanisms is essential for developing strategies to prevent or diagnose such diseases. The MRN complex, composed of MRE11, NBS1, and RAD50, is among the earliest elements involved in detecting DNA damage. Upon detecting DNA breaks, this complex triggers a cascade of signaling events that regulate both cell cycle arrest and DNA repair. These signaling pathways are tightly controlled by various post-translational modifications, notably ubiquitination. Although several ubiquitin ligases have been implicated in different stages of the DNA damage response, our knowledge remains limited. In this study, we reveal that βTrCP, a substrate-recognizing subunit of the SCF (SKP1/CUL1/F-box protein) ubiquitin ligase, interacts in vivo with the proteins of the MRN complex. These interactions occur in normally proliferating cells and are dependent on the GSK3 kinase. Moreover, we show that βTrCP enhances the recruitment of the MRN complex to chromatin through MRE11, thereby promoting the efficient DNA damage repair. Hence, alterations in βTrCP function affecting MRN dynamics could have severe consequences for the cell homeostasis.</p>","PeriodicalId":10552,"journal":{"name":"Communications Biology","volume":"8 1","pages":"1044"},"PeriodicalIF":5.2,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12254314/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144616634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
