Functional category

  • Ciliary assembly/disassembly

Function

Acts as a scaffold for the cilium disassembly complex, which includes Nde1, Aurora A, and OFD1, which is recruited to the ciliary base for timely cilium disassembly, plays a role in NPC proliferation, cilia formation, controlling the cilium axoneme and BB structure, regulates centriole duplication and elongation (30626697). Promotes the extension of the centriolar cylinder, presumably via its ability to recruit tubulin to the scent structure, studies propose that functions as a scaffold for tubulin addition (19481458).

Model organism evidence

Danio rerio (1 reference)

In addition, they both have been characterized as ciliopathy genes.

Drosophila (2 references)

We conclude that Ana1 helps recruit Polo to mother centrioles to specifically promote mitotic centrosome assembly and centriole elongation in G2, but not centriole duplication, centriole disengagement or cilia assembly.

Like the other Drosophila sensory organs, the mechanosensory bristles consist of a bipolar neuron and two tandemly aligned centrioles, the distal of which nucleates the ciliary axoneme and represents the starting point of the ciliary rootlets.
