As a component of the PP2A holoenzyme, the B56 regulatory subunit confers substrate specificity, primarily through interactions with the conserved LxxIxE motif on target proteins. This review highlights the molecular mechanisms by which PP2A-B56 regulates key processes in cell division, including chromosome cohesion and condensation, kinetochore-microtubule attachment, spindle assembly checkpoint (SAC) silencing, and activation of the anaphase-promoting complex/cyclosome (APC/C). In meiosis, PP2A-B56 safeguards centromeric cohesion and facilitates the transition between divisions, with recruitment strategies that differ across species. Recent studies also emphasize its role in protecting oocyte quality and fertility by maintaining chromosomal stability. Furthermore, the competition among multiple LxxIxE-containing substrates for PP2A-B56 binding introduces an additional layer of temporal and spatial regulation. Finally, we discuss how perturbations in PP2A-B56 activity contribute to chromosomal instability and tumorigenesis. Understanding of PP2A-B56's substrate recognition and regulatory dynamics provides a framework for therapeutic targeting in disorders involving defective cell division.</p>","PeriodicalId":18795,"journal":{"name":"Molecules and Cells","volume":" ","pages":"100255"},"PeriodicalIF":3.7,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144675302","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}

However, its intrinsic role in cancer cells remains largely unknown. We aim to explore the direct role of CD84 in acute myeloid leukemia (AML) progression and to clarify the underlying molecular mechanisms involved in nonhomologous end-joining (NHEJ) repair. Herein, we found that CD84 is frequently upregulated in various types of AML and leukemia initiation cells (LICs)-enriched cells. Knockdown or blocking of CD84 significantly inhibits the growth and induces the apoptosis of AML cells. Moreover, knockdown of <em>CD84</em> significantly delays AML progression and prolongs the survival of the xenografted mice in vivo. Mechanistically, CD84 promotes the expression of NHEJ core factors by recruiting SAP and activating the AKT signaling pathway. Knockdown of <em>CD84</em> inhibits NHEJ repair in AML cells via regulating the expression of NHEJ core factors, including <em>PRKDC</em>, <em>LIG4</em>, <em>XRCC5</em>, and <em>DCLRE1C.</em> Subsequently, this leads to double-strand breaks accumulation and cell apoptosis. Importantly, CD84 is required for the proliferation and self-renewal of human LICs. In conclusion, CD84 plays important roles in AML growth and progression through promoting NHEJ repair. Targeting CD84 may be a potential approach for inhibiting AML development and eliminating LICs.</div></div>","PeriodicalId":18795,"journal":{"name":"Molecules and Cells","volume":"48 9","pages":"Article 100253"},"PeriodicalIF":3.7,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144601023","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}

However, all of the previous studies have predominantly focused on isoform 1 (the full-length form), which consists of 566 amino acids. Here, we show that a shorter isoform, which is 308 amino acids lacking most of the N-terminus (human isoform 4; mouse isoform 3; ΔN-RNF220), is the predominant and ubiquitously expressed variant that warrants functional investigation. Both isoform 1 and ΔN-RNF220 are expressed in the brain; however, ΔN-RNF220 is the major isoform expressed in all other tissues in mice. Consistently, H3K4me3 ChIP-seq data from ENCODE reveal that the transcription start site for ΔN-RNF220 demonstrates broader and stronger activity across human tissues than that of isoform 1. ΔN-RNF220 produces 2 peptides (4a and 4b) through alternative translation initiation, with isoform 4b displaying distinct subcellular localization, subnuclear structures and interaction with a nuclear protein WDR5. Notably, during embryonic stem cell differentiation into neural stem cells, isoform 1 expression increases, whereas ΔN-RNF220 expression decreases. In murine myoblasts, ΔN-RNF220 is the sole expressed isoform and is required for MyoD and myogenin expression, as well as for muscle differentiation. Our findings highlight ΔN-RNF220 as the ubiquitously and highly expressed variant, likely playing a fundamental role across tissues while exhibiting functional differences from isoform 1. These results emphasize the critical importance of ΔN-RNF220 in future studies investigating the biological functions of RNF220.</div></div>","PeriodicalId":18795,"journal":{"name":"Molecules and Cells","volume":"48 9","pages":"Article 100250"},"PeriodicalIF":3.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560537","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}
