While the ubiquitin-conjugating enzyme E2 S (UBE2S) has been investigated in nonsmall cell lung cancer (NSCLC), its expression, functional roles, and underlying mechanisms in SCLC remain largely undefined. This study aims to elucidate the contribution of UBE2S to SCLC pathogenesis, metabolic reprogramming, and cellular plasticity.  \nMethods UBE2S expression was analyzed using public databases (TCGA, GEO, LinkedOmics, TIMER, UALCAN, etc.) and validated by immunohistochemistry on lung cancer tissue microarrays. Gain-and loss-of-function experiments were conducted in SCLC cell lines. Multi-omics approaches—including single-cell RNA sequencing (scRNA-seq), proteomics, metabolomics, and immunoprecipitation-mass spectrometry (IP-MS)—were employed. Virtual screening was performed against the UBE2S structure to identify potential inhibitors. Statistical significance was assessed using Student’s t-test, ANOVA or adjusted p-values as appropriate.  \nResults UBE2S was significantly upregulated in SCLC compared to NSCLC, with protein levels escalating from lungsquamous cell carcinoma (LUSC) to lung adenocarcinoma (LUAD) to SCLC. Elevated UBE2S expression correlated with advanced stage in both LUAD and SCLC. Functional studies in vitro and in vivo demonstrated that UBE2S promotes SCLC proliferation and cell cycle progression by driving G1/S transition. ScRNA-seq revealed specific enrichment of UBE2S in SCLC cells and implicated it in NSCLC-to-SCLC phenotypic plasticity. Integrated proteomic and metabolomic analyses indicated that UBE2S remodels metabolism, activating pathways such as folate and amino acid biosynthesis. IP-MS identified the transcription factor DLX6 as a novel UBE2S interactor, with UBE2S overexpression reducing DLX6  \n†Xiaodong Yan, Shouqiang Pan and Jin Zhang contributed equally to this article.  \n*Correspondence: Haixia Huang [haixiah@ccmu.edu.cn](haixiah@ccmu.edu.cn)[ ](haixiah@ccmu.edu.cn)Yi Zhang  \n[zhangyixwhosp@xwh.ccmu.edu.cn](zhangyixwhosp@xwh.ccmu.edu.cn)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2026.
