Function
Required for the maintenance of centromeric cohesion during interkinesis, until meiosis II (PubMed:24206843, PubMed:26272661). Required for regular configuration and segregation of sister chromatids in meiosis II (PubMed:24506176). Also required for centromere cohesion during meiosis I (PubMed:26272661). Involved in spindle organization at the end of telophase I and in meiosis II (PubMed:24506176). Required to prevent precocious release of pericentromeric cohesins during meiosis, but not for cohesion establishment and monopolar orientation of kinetochores at meiosis I (PubMed:24206843). Involved also in somatic development (PubMed:24206843). Regulates mitotic cell division and ploidy stability in somatic cell types (PubMed:24506176). May be involved in the organization of microtubules dynamics (PubMed:24506176). Involved in abiotic stresses and mono- or divalent ions tolerance and may play a role in maintaining meristematic activity under saline conditions (PubMed:24134393). PANS1 and GIG1 are part of a network linking centromere cohesion and cell cycle progression through control of APC/C activity (PubMed:26272661). Regulates the number of dividing cells in root meristem and is necessary for the anaphase onset control through an APC/C-mediated pathway (PubMed:26261921). Involved in maintaining correct chromosome arm cohesion under stress conditions (PubMed:26261921).
