Ephrin-A4 cDNA clones.

Amino acid sequences of ephrin-A4 (m) and ephrin-A4 (s) and ephrin-A4 gene structure. (A) Comparison of the amino acid sequences of ephrin-A4 (m) and ephrin-A4 (s). Amino acid numbering is depicted on the right. (B) Schematic presentation of the exon-intron organization of the ephrin-A4 gene. Exons are boxed. The size of the exons in bp are indicated by numbers in the boxes. Shaded sub-box in exon IV denotes the part of the mRNA that is spliced out in the ephrin-A4 (s) variant. *Denotes translation stop codon in the ephrin-A4 (m) sequence. **Denotes translation stop codon in the ephrin-A4 (s) sequence. (C) Sequences of exon-intron junction and the size of the introns. Capital letters denote the exons, and small letters denote the introns.
