The DD5 gene of the decapod crustacean Penaeus japonicus encodes a putative exoskeletal protein with a novel tandem repeat structure.
A gene, named DD5, was identified in the penaeid prawn Penaeus japonicus and its cDNA cloned and sequenced. DD5 is expressed in the epidermal cells underlying the exoskeleton and the transcripts are detected specifically during the postmolt stage of the molt cycle. Sequence analysis of the conceptual protein product suggests that the DD5 protein is a component of the exoskeleton. The bulk of the protein consists of tandem repeats of a unit sequence of approximately 100 amino acids. The repeated sequences are highly homologous to one another and each of them includes a variant of the Rebers--Riddiford consensus sequence.
