    text
  • nuclear matrix protein in interphase and distributes to the spindle poles during mitosis
  • restricted localization of GPSM2 and NUMA1 in the lateral belt is instructive for the planar alignment of the mitotic spindle, and required for its planar maintenance
  • basic FUNCTION
  • required for spindle-pole assembly and maintenance
  • formation of spindle-poles, dynein, dynactin dependent
  • cell cycle-related protein essential for normal mitosis that is degraded in early apoptosis
  • intact NUMA1 is a structural element in maintaining nuclear integrity
  • functions as an essential tether linking bulk microtubules of the spindle to centrosomes
  • plays a specific role in the organization of the mitotic spindle
  • may provide structural support in the interphase nucleus by contributing to the organization of chromatin
  • critical functions for NUMA1, DCTN1 and GPSM2 in mammalian development
  • NUMA1, DCTN1 and GPSM2 are involved in spindle orientation regulation
  • plays a central role in the assembly and maintenance of spindle poles
  • might contribute to the maintenance of spindle morphology in somatic cell nuclear transfer embryos
  • CELLULAR PROCESS cell cycle, division, mitosis
