Cloning and sequence analysis of Hoxa-11a gene from zebrafish (Danio rerio)

Based on the published sequence data, coding sequence of zebrafish Hoxa-11a gene was amplified by PCR, cloned and sequenced. The acquired Hoxa-11a gene, which was comprised of 1581 bp, including 622 bp exon 1726 bp intron and 233 bp exon 2, encoding 284 amino acids. Compared with Hoxa-11 proteins fr...

Description
Summary:Based on the published sequence data, coding sequence of zebrafish Hoxa-11a gene was amplified by PCR, cloned and sequenced. The acquired Hoxa-11a gene, which was comprised of 1581 bp, including 622 bp exon 1726 bp intron and 233 bp exon 2, encoding 284 amino acids. Compared with Hoxa-11 proteins from human, mouse, chick, clawed frog, and coelacanth, homologies ware 50.0%, 51.3%, 53.3%, 56.7% and 59.7%, respectively. Besides the homeobox, two highly conserved regions in exon 1 and two highly conserved DNA sequences in intron were found. The size variation of Hoxa-11a genes among varous animals is inferred to be primarily caused by accumulation of alanine repeats and of flanking segments rich in glycine and serine in exon 1.
