title: Cloning of a somatolactin-encoding cDNA from sole (Solea senegalensis).
abstract: From a Solea senegalensis cDNA expression library, clones encoding somatolactin (SL), a new pituitary hormone belonging to the growth hormone/prolactin family, were isolated and analyzed. Northern blot analysis showed a unique 1.0-kb mRNA species. The sole SL 778-bp cDNA encoded full-size S. senegalensis SL (ssSL) (230 amino acids), including seven Cys and two potential glycosylation sites. A consensus polyadenylation signal, AATAAA, was found. Protein homology and DNA sequence alignment of SL cDNAs from other evolutionarily distant marine fishes suggest that the SL sequence is highly conserved.
