Characterization of ELC interacting kinases.A NEK9 and CamK2G RNA expression in human total RNA tissue panel. Ribosomal protein large subunit P0 (RPLP0) was used as housekeeping gene. B NEK9 (left panel) and CamK2G (right panel) protein expression in piscine and human heart tissue to detect cross-species applicability. C mRNA expression profile of NEK9 and CamK2G in different human tissues from 4 weeks post-conception to adulthood68. D, E Relationship of NEK9-ELC binding efficiency on intracellular Ca2+-concentration. NEK9-ELC interaction was analyzed after overexpression of myc-tagged ELC protein in human cells followed by specific immunoprecipitation (IP) and immunoblot (IB) analysis (D). Ca2+-influx was obtained by ionophore stimulation. Quantification of NEK9-ELC interaction dependent on Ca2+-influx illustrated as the averaged intensity of precipitated NEK9 protein normalized to actin protein expression of input protein lysate (E). Data are mean ± SD (n = 3). **P < 0.01 by the analysis of ordinary one-way ANOVA followed by Bonferroni’s multiple comparisons test.
