Summary: Enables chromatin binding activity and protein kinase binding activity. Involved in several processes, including G2/M transition of mitotic cell cycle; chromosome organization; and replication-born double-strand break repair via sister chromatid exchange. Located in condensed nuclear chromosome and mitochondrion. Part of mitotic cohesin complex. Used to study Cornelia de Lange syndrome and Roberts syndrome. Human ortholog(s) of this gene implicated in Cornelia de Lange syndrome; Cornelia de Lange syndrome 4; endometrial cancer; hepatocellular carcinoma; and lung non-small cell carcinoma. Orthologous to several human genes including RAD21L1 (RAD21 cohesin complex component like 1). [provided by Alliance of Genome Resources, Dec 2024]

DNA passes through cohesin's hinge as well as its Smc3-kleisin interface.

Cohesin dysfunction results in cell wall defects in budding yeast.
Title: Cohesin dysfunction results in cell wall defects in budding yeast.
The authors show here that Scc2 also actively maintains cohesin on chromosomes during G1 in S. cerevisiae cells. It does so by blocking a Wapl-independent release reaction that requires opening the cohesin ring at its Smc3/Scc1 interface as well as the D loop of Smc1's ATPase.
Title: Scc2 counteracts a Wapl-independent mechanism that releases cohesin from chromosomes during G1.
We demonstrate that this conserved domain is required for DNA binding by Scc3-Scc1 in vitro, as well as for the enrichment of cohesin on chromosomes and for cell viability. These findings suggest that the Scc3-Scc1 DNA-binding interface plays a central role in the recruitment of cohesin complexes to chromosomes and therefore for cohesin to faithfully execute its functions during cell division.
Title: Structural basis for Scc3-dependent cohesin recruitment to chromatin.
budding yeast Plk1, Cdc5, is pre-deposited onto cohesin engaged in cohesion on chromosome arms in G2/M phase cells. The Cdc5-cohesin association is mediated by direct interaction between the polo-box domain of Cdc5 and Scc1 phosphorylated at multiple sites in its middle region.
Title: Physical Association of Saccharomyces cerevisiae Polo-like Kinase Cdc5 with Chromosomal Cohesin Facilitates DNA Damage Response.
the integrity of the Pds5-Scc1 interface is indispensable for the recruitment of Pds5 to cohesin, and that its abrogation results in loss of sister chromatid cohesion and cell viability.
Title: Structure of the Pds5-Scc1 Complex and Implications for Cohesin Function.
Study shows that cohesin's release from the DNA is mediated by disengagement of the Smc3/Scc1 interface involving interaction between the SMC ATPase heads and is inhibited by Smc3 acetylation.
Title: Releasing Activity Disengages Cohesin's Smc3/Scc1 Interface in a Process Blocked by Acetylation.
Studied the function of Mcd1 in meiosis by ectopically expressing Mcd1 during early meiotic prophase I in Saccharomyces cerevisiae.
Title: Mitotic cohesin subunit Mcd1 regulates the progression of meiotic recombination in budding yeast.
We show that residues Y371 and K372 within the SCD are critical for viability and chromosome condensation but dispensable for cohesion. However, scc3 Y371A and scc3 K372A bind normally to Mcd1
Title: A conserved domain in the scc3 subunit of cohesin mediates the interaction with both mcd1 and the cohesin loader complex.
In the linker region of Mcd1p, we identified a novel evolutionarily conserved 10-amino acid cluster, termed the regulation of cohesion and condensation (ROCC) box. The ROCC box is required for the establishment of condensation.
Title: ROCC, a conserved region in cohesin's Mcd1 subunit, is essential for the proper regulation of the maintenance of cohesion and establishment of condensation.
