Conservation of a pair of serpin 2 genes and their expression in Amphiesmenoptera
Original language description
Silk secreted by the larvae of Hydropsyche angustipennis (Trichoptera) contains serpins HaSerp2A and HaSerp2B that are homologous to serpin 2 known from several lepidopterans and some other insects. The gene HaSerp2A is 2684 bp downstream from the HaSerp2B gene. The genes possess identical exon/intron segmentation (9 exons) and their sequences are nearly identical: only 8 out of 1203 nt differ in the coding region, 4 out of 567 nt in the introns and 2 out of 52 nt in 3' UTR. Both genes are highly expressed in the silk glands whereas expression in larval carcass devoid of the silk glands is hard to detect. Translation products of the genes consist of 401 amino acids, are 98.8% identical, and are secreted as 45 kDa proteins into silk. Homologous genes insimilar tandem arrangement occur on chromosome 15 of Bombyx mori (Lepidoptera). The upstream gene BmSerp2B is modified in several exons and does not seem to produce functional mRNA. The gene BmSerp2A contains two copies of exon 9, of whi
