BioPAX pathway converted from "Cohesin binds PDS5 and WAPAL" in the Reactome database. Cohesin binds PDS5 and WAPAL Cohesin binds PDS5 and WAPAL WAPAL (WAPL) and PDS5 proteins (PDS5A and/or PDS5B) are associated with cohesin throughout most of the cell cycle (Kueng et al. 2006, Gandhi et al. 2006). FGF motifs present in the N-terminal region of WAPAL participate in WAPAL binding to PDS5 and cohesin subunits RAD21, STAG1 (SA1) and STAG2 (SA2) (Shintomi and Hirano 2009).

Central component of cohesin complex. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis. Involved in DNA repair via its interaction with BRCA1 and its related phosphorylation by ATM, or via its phosphorylation by ATR. Works as a downstream effector both in the ATM/NBS1 branch and in the ATR/MSH2 branch of S-phase checkpoint.SUBUNIT Forms a heterodimer with SMC3 in cohesin complexes (PubMed:22628566). Cohesin complexes are composed of the SMC1 (SMC1A or SMC1B) and SMC3 heterodimer attached via their SMC hinge domain, RAD21 which link them, and one STAG protein (STAG1, STAG2 or STAG3), which interacts with RAD21 (PubMed:11076961).
