    CATEGORY structural protein
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytoskeleton,microtubule,mitotic spindle
  • 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

    a component
  • part of dynactin complex required for the cytoplasmic dynein-driven movement of organelles along microtubules
    small molecule
  • ACTR1B
  • cytoplasmic dynein, ARP1 of the dynactin complex
  • interacting with tankyrases (interaction contributing to colocalization of tankyrase and NUMA1 at mitotic spindle poles)
  • interacting with HTT (regulates spindle orientation by ensuring the proper localization of the DCTN1 subunit of dynactin, dynein and NUMA1)
  • NUP188 interacts with NUMA1, which plays an instrumental role in focusing microtubules at centrosomes, and NUMA1 localization to spindle poles is perturbed in NUP188-depleted cells (pMID: 23551833)
  • NUMA1 anaphase localization is independent of GPSM2 and EPB41 interactions, revealing two distinct mechanisms responsible for NUMA1 cortical recruitment at different stages of mitosis
  • TBK1 binds to the centrosomal protein CEP170 and to the mitotic apparatus protein NUMA1, and both CEP170 and NUMA1 are TBK1 substrates
