The sequence for bovine link protein cDNA, including 108 bases of the 5' untranslated region (UTR) and 768 nucleotides of the 3' UTR, was determined from polymerase chain reaction products and bovine articular chondrocyte cDNA clones. The deduced primary structure for bovine link protein predicts a protein 354 amino acid residues in length. Comparative analysis with link protein sequence from several other species revealed overall high conservation of protein coding sequence. High nucleotide sequence conservation was observed within the extensive 5' and 3' UTRs of bovine, human, pig, chick and rat link protein mRNA. As evidence that the UTRs might play a role in regulation of link protein mRNA turnover, multiple occurrences of the adenosine-uridine binding factor motif A(Un)A were found to be conserved between species within 3' UTRs. A polyadenylation signal was conserved between the bovine and chicken sequence, use of which would result in the smallest of multiple bovine link protein mRNA species observed by Northern blot analysis.
