¹For each Ly49 gene the data shows the total number of RACE cDNA clones obtained from either cultured or fresh cells, and the percentage of these that originated in exon -1b (E-1b), exon 1 (E1), the region around the intron 1/exon 2 boundary upstream of the ATG start codon (I1/E2), in exon 2 downstream of the ATG start codon (E2 No ATG), or downstream of exon 2 (>E2), together with the total percentage of transcripts that initiated downstream of the normal translational start codon in exon 2 (% No ATG).
