The name “structural mRNA” had been coined in 2005 by Kloc et al. (2005) following discovery that the messenger RNAs (mRNAs) present in frog Xenopus laevis oocytes can have a dual, translational and nontranslational (structural) function (Kloc et al. 2005). These investigators found that maternal VegT mRNA present in the vegetal hemisphere of Xenopus oocytes besides a translational function in the production of VegT protein – a transcription factor regulating endoderm and mesoderm formation in the embryo (Kofron et al. 1999; Zhang et al. 1998) has also an independent, protein-unrelated, function (Heasman et al. 2001; Kloc et al. 2005, 2007, 2011a, b) in the organization and polymerization of cytokeratin filaments in the oocyte (Kloc 2009; Kloc et al. 2005, 2007, 2011a, b). Following this discovery, other structural mRNAs have been described in Drosophila, Xenopus, and HeLa cells (Blower et al. 2005, 2007; Jenny et al. 2006; Kanke et al. 2015;...
