Regulator of sister chromatid cohesion in mitosis which negatively regulates cohesin association with chromatin. Involved in both sister chromatid cohesion during interphase and sister-chromatid resolution during early stages of mitosis. Couples DNA replication to sister chromatid cohesion. Cohesion ensures that chromosome partitioning is accurate in both meiotic and mitotic cells and plays an important role in DNA repair.
Tissue specificity: Isoform 1 is highly expressed in uterine cervix tumor. Isoform 2 is widely expressed with a high level in skeletal muscle and heart.
Function:
Regulator of sister chromatid cohesion in mitosis which negatively regulates cohesin association with chromatin. Involved in both sister chromatid cohesion during interphase and sister-chromatid resolution during early stages of mitosis. Couples DNA replication to sister chromatid cohesion. Cohesion ensures that chromosome partitioning is accurate in both meiotic and mitotic cells and plays an important role in DNA repair.
Subunit:
Interacts with the cohesin complex throughout the cell cycle; interacts with both chromatin-bound and soluble pools of the complex. Interacts with RAD21; the interaction is direct. Interacts with PDS5A; the interaction is direct, cohesin-dependent and competitive with SORORIN. Interacts (via FGF motifs) with PDS5B; the interaction is direct. Interacts with SMC3. Isoform 2 interacts with Epstein-Barr virus EBNA2.
Subcellular Location:
Nucleus and Nucleus. Chromosome. Cytoplasm. Associates with chromatin through the cohesin complex during interphase. Released in the cytoplasm from nuclear envelope breakdown until anaphase, it reaccumulates in nucleus at telophase.
Tissue Specificity:
Isoform 1 is highly expressed in uterine cervix tumor. Isoform 2 is widely expressed with a high level in skeletal muscle and heart.
Similarity:
Contains 1 WAPL domain.
