In Fig. 1 and the figure legend there are errors regarding the number of amino acids in a protein. The label “ΔC Splice Variant: 364 aa” should be “ΔC Splice Variant: 442 aa” in Fig. 1. In the legend to Fig. 1, the third sentence should read: “The truncated form lacks almost the entire COOH tail (171 aa, green, red, and short black traits) but bears an extra 18 aa (light blue trait) due to inclusion of the intron between exons 10 and 11 (94).”
