Cohesin ring

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 ...
