Western blot analysis of CETN3 over-expressed 293 cell line, cotransfected with CETN3 Validated Chimera RNAi ( Cat # H00001070-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with CETN3 monoclonal antibody (M01), clone 3E6 (Cat # H00001070-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene contains four EF-hand calcium binding domains, and is a member of the centrin protein family. Centrins are evolutionarily conserved proteins similar to the CDC31 protein of S. cerevisiae. Yeast CDC31 is located at the centrosome of interphase and mitotic cells, where it plays a fundamental role in centrosome duplication and separation. Multiple forms of the proteins similar to the yeast centrin have been identified in human and other mammalian cells, some of which have been shown to be associated with centrosome fractions. This protein appears to be one of the most abundant centrins associated with centrosome, which suggests a similar function to its yeast counterpart. [provided by RefSeq
