SGOL1 Colorimetric Cell-Based ELISA

The SGOL1 Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor SGOL1 protein expression profile in cells. The kit can be used for measuring the relative amounts of SGOL1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on SGOL1.

Function

Plays a central role in chromosome cohesion during mitosis by preventing premature dissociation of cohesin complex from centromeres after prophase, when most of cohesin complex dissociates from chromosomes arms. May act by preventing phosphorylation of the STAG2 subunit of cohesin complex at the centromere, ensuring cohesin persistence at centromere until cohesin cleavage by ESPL1/separase at anaphase. Essential for proper chromosome segregation during mitosis and this function requires interaction with PPP2R1A. Its phosphorylated form is necessary for chromosome congression and for the proper attachment of spindle microtubule to the kinetochore. Necessary for kinetochore localization of PLK1 and CENPF. May play a role in the tension sensing mechanism of the spindle-assembly checkpoint by regulating PLK1 kinetochore affinity. Isoform 3 plays a role in maintaining centriole cohesion involved in controlling spindle pole integrity. Involved in centromeric enrichment of AUKRB in prometaphase.

Subcellular Location

Nucleus. Chromosome, centromere. Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, spindle pole. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Localizes to the inner centromere throughout prophase until metaphase and disappears at anaphase (PubMed:16541025) . Centromeric localization requires the presence of BUB1 and the interaction with PPP2R1A (PubMed:16580887) (PubMed:16541025) (PubMed:15604152) . Colocalizes with NEK2 at the kinetochore (PubMed:17621308) . Colocalizes with and SS18L1 at the kinetochore (PubMed:16582621) . Phosphorylation by AUKRB and the presence of BUB1 are required for localization to the kinetochore (PubMed:17617734) . Isoform 1 primarily localizes to kinetochores during G2 phase and mitotic prophase, metaphase, and anaphase and does not appear to be associated with kinetochores during late mitosis (PubMed:16582621) . Isoform 3 is found at the centrosome in interphase and at spindle poles in mitosis and its spindle pole localization is PLK1 dependent (PubMed:16582621) . Isoform 3 does not localize to kinetochores during any stages of the cell cycle (PubMed:16582621) .
