MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 and is phosphorylated by polo-like kinase 1, and functions in maintaining microtubule organization and cell morphology. The human genome contains a putative transcribed pseudogene. Several alternatively spliced transcript variants of this gene have been found, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

Protein Function and Prediction

Cep170 is a microtubule-associated phosphoprotein that is necessary to target kinesin-like protein Kif2b to the mitotic spindle (1). Cep170 is proposed to also control cell morphology and can function as a marker for centriole maturation during the cell cycle (2). Knockdown of Cep170 did not alter the centrosomal recruitment of any protein tested (γ-tubulin, centrin-2, polyglutamylated tubulin [GT335], C-Nap1, Nek2, Plk1, and Aurora-A) (2). However, changes to microtubule organization and the shape of interphasic cells was observed (2).

Expression/Localization

Cep170 is a ubiquitously expressed protein that localizes to centrosomes and microbules during interphase and to the mitotic spindle during metaphase (1;2). Comparable amounts of Cep170 are expressed in all cell cycle stages (2).
