    text
  • colocalized with CLIPs at microtubule distal ends
  • during the mitosis, it localizes to centrosomes, the mitotic spindle, centromeres and spindle midzone
  • basic FUNCTION
  • local regulation spindle microtubule dynamics and attachment to kinetochore
  • plays a role in centrosome separation and organisation of the bipolar mitotic spindle
  • required at kinetochores for attached microtubules to exhibit normal dynamic behavior
  • cooperate with CLASP2 to ensure mitotic fidelity by regulating spindle and kinetochore function
  • required for mitotic spindle organization and kinetochore alignment
  • function as actin/microtubule crosslinkers in interphase cells and facilitate recognition of actin filaments by the plus ends of growing microtubules at the initial stages of actin-microtubule interaction
  • essential for Golgi-associated microtubule nucleation and directional migration
  • CLASP1 is required to correctly capture astral microtubules, whereas MAP4 prevents engagement of excess dynein motors, thereby protecting the system from force imbalance
  • MAP4 and the microtubule rescue factor CLASP1 are essential for maintaining spindle position and the correct cell-division axis in human cells

    protein
  • CLIP2 and CLIP1, binding to microtubules and cooperate to direct the microtubule network and regulating cellular asymmetry
  • MAPRE1
  • interacting with GSK3A (controls axon growth via CLASP1-mediated regulation of growth cone microtubules)
  • estrogen receptor binding CpG island, EB1
  • PRC1 to the central spindle at early anaphase onset
  • is a substrate for the BRCA1, suggesting that its modification selectively triggers CHEK1 activation for the homology-directed repair of a subset of genotoxic lesions
