Summary
This gene encodes a centrosome and spindle pole associated protein. The encoded protein plays a role in cell-cycle progression and spindle organization, regulates cytokinesis, interacts with Nephrocystin 8 and is required for cilia formation. Mutations in this gene result in primary cilia abnormalities and classical Joubert syndrome. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

    Description
    Transcript Variant: This variant (2) contains a distinct 5' UTR, and lacks an in-frame portion of the 5' coding region and an internal in-frame exon, compared to variant 1. The resulting isoform (2, also known as CSPP) has a shorter N-terminus and lacks an internal segment, compared to isoform 1.
