What is "rootletin"

Rootletin also known as ciliary rootlet coiled-coil protein (CROCC) is a protein that in humans is encoded by the CROCC gene. Rootletin is a component of the ciliary rootlet, and, together with CEP68 and CEP250, is required for centrosome cohesion.

Rootletin is an important protein in the ciliary rootlet, particular for the structure and can be considered an important protein in mitosis as it is a centrosome linker.
