Fig. 1. Amino acid sequence of rat p66 and its alignment with huACF. P66 cDNA was amplified from total rat liver poly A mRNA. The predicted amino acid sequence has been aligned with that of huACF. For clarity, only those amino acids not identical to huACF are shown, with shading indicating a conservative substitution in the rat p66 sequence. The location of the RNP2 and RNP1 sequences of the three RRMs are indicated. The site of an eight amino acid insertion found in the human ASP homolog and the location of the 15 amino acid sequence used to produce peptide-specific antibodies are also indicated.
