NCAPD3 (Non-SMC Condensin II Complex Subunit D3) is a Protein Coding gene. Among its related pathways are DNA Damage and Cell Cycle, Mitotic. Condensin complexes I and II play essential roles in mitotic chromosome assembly and segregation. Both condensins contain 2 invariant structural maintenance of chromosome (SMC) subunits, SMC2 (MIM 605576) and SMC4 (MIM 605575), but they contain different sets of non-SMC subunits. NCAPD3 is 1 of 3 non-SMC subunits that define condensin II.
