The cohesin complex is essential for proper chromosome structure and gene expression. Defects in cohesin subunits and regulators cause changes in cohesin complex dynamics and thereby alter three-dimensional genome organization. However, the molecular mechanisms that drive cohesin localization and function remain poorly understood. In this study, we observe that loss of WIZ causes changes to cohesin localization that are distinct from loss of the known WIZ binding partner G9a. Whereas loss of WIZ uniformly increases cohesin levels on chromatin at known binding sites and leads to new, ectopic cohesin binding sites, loss of G9a does not. Ectopic cohesin binding on chromatin after the loss of WIZ occurs at regions that are enriched for activating histone modifications and transcription factors motifs. Furthermore, loss of WIZ causes changes in cohesin localization that are distinct from those observed by loss of WAPL, the canonical cohesin unloading factor. The evidence presented here suggests that WIZ can function independently from its previously identified role with G9a and GLP in heterochromatin formation. Furthermore, while WIZ limits the levels and localization pattern of cohesin across the genome, it appears to function independently of WAPL-mediated cohesin unloading.
