[5][6] The product of this gene is a component of the centrosome, a non-membraneous organelle that functions as the major microtubule organizing center in animal cells.

During interphase, the encoded protein localizes to the sub-distal appendages of mature centrioles, which are microtubule-based structures thought to help organize centrosomes.

During mitosis, the protein associates with spindle microtubules near the centrosomes.

The protein interacts with the intraflagellar transport protein 81 (IFT81), the SH3-domain containing protein PRAX-1, and is phosphorylated by cyclin dependent kinase 1 (Cdk1) and polo-like kinase 1 (PLK1), and functions in maintaining microtubule organization, cell morphology and cilium stability.

[5] The human genome contains a putative transcribed pseudogene.
