The metalloproteinase ADAM10 has attracted attention because it cleaves a growing amount of protein substrates close to the extracellular membrane leaflet. The process known as \"ectodomain shedding\" controls the turnover of certain transmembrane proteins that are essential for receptor signaling and cell adhesion. It may trigger nuclear transport, intramembrane proteolysis, and cytoplasmic domain signaling. Additional human illnesses linked to ADAM10 include cancer, immune system malfunction, and neurodegeneration. The difficulty in targeting proteases for medicinal reasons stems from the many substrates that these enzymes, particularly ADAM10, have. It is usually necessary to precisely identify the therapeutic beneficial window of use since blocking or accelerating a particular protease activity is linked with undesirable side effects. More knowledge of the regulatory pathways governing ADAM10 expression, subcellular localization, and activity will probably lead to the identification of viable therapeutic targets, enabling more targeted and precise manipulation of the enzyme's proteolytic activity.</p>","PeriodicalId":10859,"journal":{"name":"Current protein & peptide science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143413671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The co- LLPS (also known as co-condensation) and co-aggregation of different disease-related proteins have been proposed as a potential molecular mechanism for combined neuropathology. Here, we reviewed the current state of knowledge regarding the co-aggregation and co-condensation of various amyloid proteins, including Aβ, tau, α-synuclein, TDP-43, FUS, and hnRNPA/B protein family, C9orf72 dipeptide repeats and prion protein. We briefly introduced the epidemiological correlation among different neurodegenerative diseases and specifically presented recent experimental findings about co-aggregation and co-condensation of two different amyloid proteins. Additionally, we discussed computational studies focusing on the molecular interactions between amyloid proteins to offer mechanistic insights into the co-LLPS and co-aggregation processes.

Defective protein folding has been implicated in a wide range of clinical conditions, including neurodegenerative and metabolic disorders. It is now well understood that the pathogenesis of neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, Huntington's disease, Amyotrophic Lateral Sclerosis, and Creutzfeldt-Jakob disease shares a common mechanism: the accumulation of misfolded proteins, which aggregate and become toxic to cells. Among the family of molecular chaperones, Heat Shock Proteins (HSPs) are highly expressed in response to cellular stress and play a pivotal role in preventing protein aggregation. Specific chaperones, particularly HSPs, are now recognized as critical in halting the accumulation and aggregation of misfolded proteins in these conditions.
