Anti-SGOL2 Antibody (Center)

Cooperates with PPP2CA to protect centromeric cohesin from separase-mediated cleavage in oocytes specifically during meiosis I. Has a crucial role in protecting REC8 at centromeres from cleavage by separase. During meiosis, protects centromeric cohesion complexes until metaphase II/anaphase II transition, preventing premature release of meiosis-specific REC8 cohesin complexes from anaphase I centromeres. Is thus essential for an accurate gametogenesis. May act by targeting PPP2CA to centromeres, thus leading to cohesin dephosphorylation (By similarity) . Essential for recruiting KIF2C to the inner centromere and for correcting defective kinetochore attachments.

This SGOL2 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 391-419 amino acids from the Central region of human SGOL2.

Nucleus. Chromosome, centromere. Chromosome, centromere, kinetochore {ECO:0000250|UniProtKB:Q7TSY8}. Note=During meiosis I, accumulates at centromeres during diplotene, and colocalizes differentially with the cohesin subunits RAD21 and REC8 at metaphase I centromeres (By similarity) . SGO2 and RAD21 change their relative distributions during telophase I when sister-kinetochore association is lost (By similarity) . During meiosis II, it shows a striking tension- dependent redistribution within centromeres throughout chromosome congression during prometaphase II, as it does during mitosis (By similarity) . In Hela cells, localizes at centromeres throughout prophase until metaphase and disappears at anaphase (PubMed:17485487) Centromeric localization requires the presence of BUB1 and AUKRB (PubMed:17485487) . {ECO:0000250|UniProtKB:Q7TSY8, ECO:0000269|PubMed:17485487}
