Sequence alignment of Gβ1 (UniProtKB accession ID: P62873) vs RACK1 orthologues from Homo sapiens (P63244), Drosophila melanogaster (O18640), Arabidopsis thaliana (O24456), Saccharomyces cerevisiae (P38011) and Tetrahymena thermophila (E6PBV0). This alignment is similar to that presented by Ullah et al  but revised to include the sequence of the T. thermophila protein. WD-repeats and secondary structural elements are defined above the sequences. The percentage sequence identity between human RACK1 and the orthologues from other species is defined at the end of the alignment. The homology index for the proteins (excluding Gβ1) is presented below the sequence, where fully conserved residues are marked with an asterisk; conservative and semiconservative positions are marked with colons and periods respectively. Residues marked in red in the yeast sequence engage rRNA in the eukaryotic 40S ribosomal subunit (see text).
