- Epigenetic regulation involves the coordinated interplay of diverse proteins. To systematically explore these combinations, we present COMBINE (combinatorial interaction exploration), a high-throughput platform that tests over 50,000 pairs of epigenetic effector domains up to 2,094 amino acids in length for their ability to modulate endogenous human gene transcription. COMBINE reveals diverse synergistic interactions between epigenetic protein domains, including a potent KRAB-L3MBTL3 fusion that increases the effective targeting window, enhances gene silencing in dose-limited conditions, and enables robust dual-directional CRISPR perturbation. Inducible screening shows DNA methylation modifiers are essential for epigenetic memory, with distinct combinations driving long-term repression and activation. This systematic analysis of pairwise domain interactions advances our understanding of epigenetic crosstalks and the development of next-generation epigenome editing tools. More broadly, COMBINE offers a generalizable platform to functionally characterize combinatorial biological processes at scale. - Source: PubMed

Jiang PanFang YanfeiLiu ZhengyeDu HanzeBai XiaoyinChen HaotianMi Jiarui - Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age-related diseases and might contribute to the development of both sarcopenia and frailty. In this study, we investigated the contribution of multi-omics data to sarcopenia, frailty, lean mass index (LMI) and handgrip strength in an elderly Lithuanian population. A total of 204 participants (age 82.2 ± 7.6 years) were included, comprising 122 individuals diagnosed with sarcopenia and/or frailty and 82 healthy, community-dwelling older adults. The results showed that LMI was associated with various health and lifestyle factors. Two genetic variants, CLIC5 rs75652203 and GHITM rs17102732, were found to be significantly associated with handgrip strength at the genome-wide level. Additionally, 12 polymorphisms previously linked to sarcopenia were replicated in relationship to LMI: BOK rs76993203, VAMP5 rs1374370, TMEM18 rs12714414, SFMBT1 rs36033494, BANK1 rs13136118, TET2 rs2647239, FOXO3 rs9384679, L3MBTL3 rs13209574, ZFAT rs13267329, CEP57 rs35793328, PCGF2 rs1985352 and MC4R rs66922415. Furthermore, several genes, many of which are involved in immune system processes, were significantly enriched with differentially methylated sites associated with LMI. Shorter telomeres were also associated with both sarcopenia and frailty. Notably, a significant relationship was observed between telomere length and methylation levels in genes related to lifestyle traits and the risk of developing these conditions. These findings provide new insights into the biological mechanisms underlying sarcopenia and frailty, underscoring the important roles of genetic and epigenetic factors in their pathogenesis among older adults. - Source: PubMed

The chromatin-binding protein SAMD1 [sterile alpha motif (SAM) domain-containing protein 1] binds to unmethylated CpG-rich DNA utilizing its N-terminal winged-helix (WH) domain. Additionally, its C-terminal SAM domain, which mediates interactions with itself and with L3MBTL3, is crucial for chromatin binding. The precise role of the SAM domain in this process remains unclear. Using structural analyses, we elucidated the distinct homopolymerization modes within the SAM domains of L3MBTL3 and SAMD1, alongside their heterodimerization architecture. Interestingly, SAMD1 necessitates not only the WH and SAM domain but also a proline/alanine-rich intrinsically disordered region (IDR) for efficient chromatin binding. The IDR is essential for the ability of SAMD1 to form large polymers, with its functionality determined by integrity rather than the specific sequence. Mutagenesis studies underscore the critical role of arginines within the IDR for polymerization, chromatin binding, and the biological function of SAMD1. These findings propose a model in which structured and unstructured regions of SAMD1 cooperate in a coordinated fashion to facilitate chromatin binding. This work provides new insights into the diverse mechanisms transcription factors employ to interact with chromatin and regulate gene expression. - Source: PubMed
