Cytoplasmic linker associated protein 1, also known as CLASP1, is a protein which in humans is encoded by the CLASP1 gene. ^[5]

Function

CLASP1 belongs to a family of microtubule-associated proteins involved in attachment of microtubules to the cell cortex in animals ^[6] and plants. ^[7] CLASPs, such as CLASP1, interact with CLIPs (e.g., CLIP1). In animal cells, CLASP1 is involved in the regulation of microtubule dynamics at the kinetochore and throughout the spindle. ^{[5] [8]} CLASP1 controls the interactions of astral microtubules with the cell cortex in mitosis, which is important for the proper positioning and orientation of the spindle. ^[9]
