Chicken chromosomal protein HMG-14 and HMG-17 cDNA clones: isolation, characterization and sequence comparison.

A cDNA clone coding for the chicken high-mobility group 14 (HMG-14) mRNA has been isolated from a chicken-liver cDNA library by screening with two synthetic oligodeoxynucleotide pools whose sequences were derived from the partial amino acid sequence of the HMG-14 protein. A chicken HMG-17 cDNA clone was also isolated in a similar fashion. Comparison of the two chicken HMG cDNA clones to the corresponding human cDNA sequences shows that chicken and human HMG-14 mRNAs and polypeptides are considerably less similar than are the corresponding HMG-17 sequences. In fact, the chicken HMG-14 is almost as similar to the chicken HMG-17 in amino acid sequence as it is to mammalian HMG-14 polypeptides. HMG-14 and HMG-17 mRNAs seem to contain a conserved sequence element in their 3'-untranslated regions whose function is at present unknown. The chicken HMG-14 and HMG-17 genes, in contrast to their mammalian counterparts, appear to exist as single-copy sequences in the chicken genome, although there appear to exist one or more additional sequences which partially hybridize to HMG-14 cDNA. Chicken HMG-14 mRNA, about 950 nucleotides in length, was detected in chicken liver RNA but was below our detection limits in reticulocyte RNA.
