Summaries for STAG2 Gene

Entrez Gene Summary for STAG2 Gene

  • The protein encoded by this gene is a subunit of the cohesin complex, which regulates the separation of sister chromatids during cell division. Targeted inactivation of this gene results in chromatid cohesion defects and aneuploidy, suggesting that genetic disruption of cohesin is a cause of aneuploidy in human cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]

CIViC summary for STAG2 Gene

GeneCards Summary for STAG2 Gene

STAG2 (Stromal Antigen 2) is a Protein Coding gene. Diseases associated with STAG2 include Laryngotracheitis and Tracheitis. Among its related pathways are SUMOylation and Mitotic Telophase/Cytokinesis. Gene Ontology (GO) annotations related to this gene include chromatin binding and binding. An important paralog of this gene is STAG1.

UniProtKB/Swiss-Prot for STAG2 Gene

  • Component of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis.

    • Interacts directly with RAD21 in cohesin complex. Cohesin complexes are composed of a heterodimer between a SMC1 protein (SMC1A or SMC1B) and SMC3, which are attached via their hinge domain, and RAD21 which link them at their heads, and one STAG protein (STAG1, STAG2 or STAG3). In cohesin complexes, STAG2 is mutually exclusive with STAG1 and STAG3.

Localization for STAG2 Gene

Subcellular locations from UniProtKB/Swiss-Prot for STAG2 Gene

Nucleus. Chromosome. Chromosome, centromere. Note=Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin probably because of phosphorylation by PLK1, except at centromeres, where cohesin complexes remain. At anaphase, the RAD21 subunit of cohesin is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation. In germ cells, cohesin complex dissociates from chromatin at prophase I, and may be replaced by a meiosis-specific cohesin complex.
