dc.titleProthymosin alpha and parathymosin: amino acid sequences deduced from the cloned rat spleen cDNAsen
heal.abstractA rat spleen cDNA library was screened for clones carrying the cDNAs for prothymosin alpha and parathymosin. Sequence analysis of a clone carrying the entire coding region for prothymosin alpha confirmed and completed the amino acid sequence for this polypeptide and established the number of amino acid residues as 111. Rat prothymosin alpha differs from human prothymosin alpha at six positions, including four substitutions and two insertions. The nucleotide sequences of the cDNAs for the rat and human polypeptides are more than 90% identical in the open reading frames, with significant homology extending into the 5' and 3' flanking regions. From the same library, we also isolated a clone carrying 80% of the coding region for rat parathymosin. The number of amino acid residues in rat parathymosin is 101, based on the sequence deduced from the cDNA insert and earlier information on the sequence in the amino-terminal portion of this polypeptide. Despite their similarity in size and amino acid composition, rat prothymosin alpha and rat parathymosin show only limited sequence homology, primarily in the segment including residues 14 through 25, where 10 of 12 positions are identical in the two polypeptides. this is also the region of significant sequence similarity to a 12-amino-acid segment in the p17 protein of the human immunodeficiency disease associated virus (HTLV-IIIB).en
