GeneCards Summary for SKA2 Gene

SKA2 (Spindle And Kinetochore Associated Complex Subunit 2) is a Protein Coding gene. Diseases associated with SKA2 include Post-Traumatic Stress Disorder. Among its related pathways are Signaling by Rho GTPases and Cell Cycle, Mitotic. Gene Ontology (GO) annotations related to this gene include microtubule binding.

UniProtKB/Swiss-Prot for SKA2 Gene

  • Component of the SKA1 complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation (PubMed:17093495, PubMed:19289083, PubMed:23085020). Required for timely anaphase onset during mitosis, when chromosomes undergo bipolar attachment on spindle microtubules leading to silencing of the spindle checkpoint (PubMed:17093495). The SKA1 complex is a direct component of the kinetochore-microtubule interface and directly associates with microtubules as oligomeric assemblies (PubMed:19289083). The complex facilitates the processive movement of microspheres along a microtubule in a depolymerization-coupled manner (PubMed:17093495, PubMed:19289083). In the complex, it is required for SKA1 localization (PubMed:19289083). Affinity for microtubules is synergistically enhanced in the presence of the ndc-80 complex and may allow the ndc-80 complex to track depolymerizing microtubules (PubMed:23085020).

    Quaternary structure:
    • Component of the SKA1 complex, composed of SKA1, SKA2 and SKA3. Forms a heterodimer with SKA1; the heterodimer interacting with SKA3. The core SKA1 complex is composed of 2 SKA1-SKA2 heterodimers, each heterodimer interacting with a molecule of the SKA3 homodimer. The core SKA1 complex associates with microtubules and forms oligomeric assemblies. Interacts directly with SKA1. Binds directly to microtubules; but with a much lower affinity than SKA1. May interact with NR3C1; the relevance of such interaction remains unclear in vivo.
