The muntjak satellite IA sequence is composed of 31-base-pair internal repeats that are highly homologous to the 31-base-pair subrepeats of the bovine satellite 1.715.
The nucleotide sequence of a cloned Muntjak satellite IA repeat unit (Muntiacus muntjak vaginalis) was determined. The repeat is 807 base pairs (bp) long. By introducing minor deletions and insertions, the whole sequence of the satellite can be arranged in 27 subrepeats of 31 bp length. Although diverged relative to each other, all subrepeats show a homology of more than 53% with the common consensus sequence. In 29 out of the 31 bp the consensus sequence of the Muntjak satellite subrepeat is identical to the 31-bp subrepeat of the bovine satellite 1.715. This suggests that both satellites are derived from a common ancestral sequence. The results have interesting implications for the evolution of the two satellites.
