gene_protein use of alternative promoters and alternative first exons for variant 1 (Cdkn2a) and variant 2 (p19Arf), both of which contain translation start sites, results in the production of two non-homologous proteins despite the fact that the transcripts share two downstream exons (exons 2 and 3)
