The etiological agent is Mycobacterium tuberculosis, an acid-fast bacillus. Drug-resistant tuberculosis poses a global challenge, with specific mycobacterial genes intricately associated with drug resistance. Numerous factors are implicated in the etiology of the condition. This review specifically aims to examine ClpCP, an ATPase belonging to the AAA + protease family, and the genes of the two-component sensor system related with disease etiology. Mycobacterium TB depends significantly on protein degradation to regulate their quantity and quality, which is crucial for its proliferation and pathogenicity involving Clp. The two-component sensor system comprises histidine kinase (HK) and response regulator (RR), which governs responses to stress situations, starvation, nutritional abundance, persistence, hypoxia, dormancy, and primarily disease pathogenesis. Within the two-component system, there exist 12 pairs, including SenX3/RegX3, PhoP/PhoR, DosR/DosS, MtrA/MtrB, and PdtaS/PdtaR, alongside 6 response regulators Rv0195, Rv0260c, Rv0818, PdtaR, Rv2884, and Rv3143 encoded in the Mycobacterium tuberculosis genome. The PhoPR genes have been extensively researched, and the pathogenicity of Mycobacterium tuberculosis (MTB) is contingent upon the sensor kinase of the PhoPR two-component regulatory system, known as PhoR. This review will examine the roles of genes related to the factors associated with mycobacterial growth and pathogenesis.</div></div>","PeriodicalId":12499,"journal":{"name":"Gene","volume":"977 ","pages":"Article 149868"},"PeriodicalIF":2.4,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145476837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
