title: Structure of a D-protein gene and amino-acid sequences of the highly repetitive D-proteins secreted by the accessory glands of the mealworm beetle.
abstract: The D-group proteins form the major component of the proteinaceous secretion of the tubular accessory glands of the yellow mealworm beetle, Tenebrio molitor. In a previous paper, we reported the sequence of two D-protein cDNAs and their inferred translation products. Both proteins contain three highly repetitive domains (A, A' and B). In this paper, we present the cDNA-inferred sequences of 8 more D-proteins, none of which contains an A' domain. We also present the structure of a D-protein gene. Southern analysis suggests that genes coding for an A' domain are relatively rare. Genes with a total of 7 or 8 (A + B domain) repeats seem most common.
