Abstract

A novel putative SINE sequence was found in a randomly selected cosmid clone of Salmo salar. The sequence (cSSML032Alu, GenBank accession number: L77085) was found to have 78% identity in 212 bp, with one Salvelinus namaycush AluI satellite sequence (GenBank accession number: U27096) and 69% identity in 197 bp, with another AluI satellite sequence from S. namaycush (GenBank accession number: U27091). Colony hybridization of cSSML032Alu to a salmon cosmid library indicated its dispersed presence in the genome, with a copy number in the range of a few thousand. Direct terminal repeats of nine bases and a potential poly(A) tail remnant identified in the S. salar cSSML032Alu sequence indicate a possible ancient retroposon unit.
