Using RT-PCR-based cDNA cloning, we identified novel splice variants of amphiphysin I, termed amph Ir, that are expressed specifically in retina. In comparison with the prototype amphiphysin I, amph Ir contained two novel insertions (inserts A and B) and one deletion. Insert A is only 9 bp in length but appears to be a determinant for the retina-specific expression. In contrast, insert B is a large domain of 1740 bp and two shorter transcripts with 3′-truncated insert B were also expressed. All the insert sequences were present as unidentified exons in the amphiphysin I gene on human chromosome 7. Western blot analysis of various rat tissues with anti-insert B antibody confirmed the presence and tissue specificity of the variant proteins.
