title: [Interaction between a novel centrosomal protein TACP1 and mitotic kinase Nek2A].
abstract: To study interaction between a novel centrosomal protein TACP1 and mitotic kinase Nek2A.
  
  
  
  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.
  
  
  
  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.
  
  
  
  Centrosomal protein TACP1 is a novel interacting protein with Nek2A, both of which are localized in centrosome during mitosis.
