Alignment of RT1-E2 protein sequences deduced from the cDNA sequences summarised in Table 1with those of other rat class I sequences. For E2b^a (acc. AJ537439), the translated sequence ends prematurely because of a frameshift at the start of exon 5 (see text). The line E2b^a* shows the notional downstream translation of the cDNA sequence if this frameshift was not present. In the sequences from which the RT1-E2^g (acc. AJ243338) sequence was compiled (p57, p4.4, p4.6), underlined residues correspond to positions that differ from all the other RT1-E2 sequences, and could therefore be due to either PCR mutations or true allelic differences. Others accession numbers are as follows: E2b^u: AJ537420, E2b^l: AJ537417, E2aⁿ (deduced from genomic): AJ315490, E2a^l: AJ276126, E2c^l: AJ537418, E2d^l: AJ537419, E2d^c: AJ537441, E^av1: AJ537440, E^u: AJ306619, A^l: L26224, A^a: M31018, A^u: X82106. Alignment of the corresponding DNA sequences is available as supplementary data or upon request.
