Centrosomes are the microtubules organizing centers of most eukaryotice cells. Centrosomes are formed of a protein matrix called the pericentriolar material and two cylindrical shape structures formed of microtubules and associated proteins called centrioles. Centrosomes are important to ensure normal bipolar spindle formation during cell division. The daughter centriole elongates from its proximal end perpendicularly to the mother centriole. At the distal end of the new forming centriole, a complex formed of CCP110 and Cep97 stops probably the elongation by acting as distal cap. In previous work our lab has found a putative Cep97 homologous protein in C. elegans as an interactor of the multifunctional polo-like kinase 1 (PLK1). In this work we screen for interactors of the Cep97 C. elegans homologous protein R02F11.4. We have found four interactions; one homotypic interaction, an interaction with SAS-5 and interactions with two proteins which are candidates to be functional homologous of CCP110.
