title: Molecular cloning and characterization of the bovine tuftelin gene.
abstract: The bovine tuftelin gene was cloned and its structure determined by DNA sequence analysis and comparison to that of bovine tuftelin cDNA. The analyses demonstrated that the cDNA contains a 1014-bp open reading frame encoding a protein of 338 residues with a calculated mol. wt of 38,630 and an isoelectric point of 5.85. These results differ from those previously published, (1991) which contained a different conceptual amino acid sequence for the carboxy terminal region and identified a different termination codon. The protein does not appear to share homology or domain motifs with any other known protein. The gene consists of 13 exons ranging in size from 66 to 1531 bp, the latter containing the encoded carboxyterminal and 3' untranslated regions. The exons are embedded in more than 28 kbp of genomic DNA. Codons are generally not divided at exon/intron borders. Several alternatively spliced transcripts were identified by DNA sequence analysis of the isolated products produced by reverse transcriptase/polymerase chain reaction.
