PDS5B

Sister chromatid cohesion protein PDS5 homolog B (PDS5B) is a protein that in humans is encoded by the PDS5B gene.^[5][6][7] It is a regulatory subunit of the Cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. The core cohesin complex is formed of SMC3, SMC1, RAD21 and either SA1 or SA2. PDS5 associates with WAPL to stimulate the release of cohesin from DNA but during DNA replication PDS5 promotes acetylation of SMC3 by ESCO1 and ESCO2.
