Guanine nucleotide-binding protein gene (GNA) isoforms expressed in X. laevis eggs. Heatmaps of RNA (top) and protein (bottom) expression levels of Gα subunits at various developmental stages of egg maturation. RNA-seq data displayed as transcripts per million (TPM), and protein data shown as nanomolar concentration. Transcript levels were obtained and compiled from Session et al. (2016), while protein concentrations were from Wühr et al. (2014) through mass spectrometry.
