WebIn humans and mice, the meiotic-specific cohesin complex assembles in a tri-partite configuration composed of the structural maintenance of chromosomes (SCC) proteins SMC1β and SMC3, the bridging or linker α-kleisin subunit Rad21, which is also bound by the stromal antigen protein STAG3. WebCohesin's Scc1, Smc1 and Smc3 subunits form a tripartite ring structure, and it has been proposed that cohesin holds sister DNA molecules together by trapping them inside its ring. To test this, we used site-specific crosslinking to create chemical connections at the three interfaces between the three constituent polypeptides of the ring ...
The cohesin ring concatenates sister DNA molecules
WebThe cohesin ring includes an ABC family ATPase, but the molecular mechanism by which the ATPase contributes to cohesin function is not yet understood. In this study, we have purified budding yeast cohesin, as … WebMay 6, 2024 · Cohesin's Scc1, Smc1, and Smc3 subunits form a tripartite ring structure, and it had been proposed that cohesin holds sister DNA molecules together by trapping them inside its ring.
