ABSTRACT
<p><b>OBJECTIVE</b>To study interaction between a novel centrosomal protein TACP1 and mitotic kinase Nek2A.</p><p><b>METHODS</b>Nek2A305-446 protein was expressed and purified in E.coli and TACP1 protein was expressed in transfected 293T cells. Pull-down assay was used to examine the interaction between Nek2A305-446 and TACP1. TACP1 and Nek2A complex was tested by co-immunoprecipitation assay with polyclonal anti-TACP1 antibody. The localization of those two proteins in Hela cells was verified by immunofluorescence.</p><p><b>RESULTS</b>TACP1 was pulled down by Nek2A305-446 protein but not by GST control. Nek2A was co-precipitated with TACP1 protein by polyclonal anti-TACP1 antibody but not by pre-immunization serum. The Immunofluorescence test showed that these two proteins formed a complex at centrosome during mitosis.</p><p><b>CONCLUSION</b>Centrosomal protein TACP1 is a novel interacting protein with Nek2A, both of which are localized in centrosome during mitosis.</p>
