Sensitization to cockroach allergens is associated with the development of asthma. Bla g 1 is a German cockroach allergen that shows allergenic cross-reactivity with American cockroach allergen, Per a 1, and has a molecular structure composed of multiple tandem amino-acid repeats. Two consecutive repeats are not identical but form a duplex that constitutes a basic molecular unit of Bla g 1. By molecular mass, purified natural Bla g 1 would contain approximately two duplexes.

Two novel toxins, Lqh6 andLqh7, isolated from the venom of the scorpionLeiurus quinquestriatus hebraeus,have in their sequence amolecular signature (8Q/KPE10) associated with a recently defined group ofa-toxins that target Na channels, namely thea-like toxins [reviewed inGordon, D., Savarin, P.,Gurevitz,M.&Zinn-Justin, S. (1998)J. Toxicol. Toxin Rev.17, 131–159]. Lqh6 and Lqh7 are highly toxic to insects and mice, and inhibit the binding of a-toxins to cockroach neuronal membranes.

Tachykinins and tachykinin-related peptides (TKRPs) play major roles in signaling in the nervous system and intestine of both invertebrates and ver-tebrates. Here we have identified cDNAs encoding precursors of multiple TKRPs from the cockroachesLeucophaea maderaeandPeriplaneta ameri-cana. All nine LemTKRPs that had been chemically isolated in earlier experiments could be identified on the precursor ofL. maderae. Four previ-ously unidentified LemTKRPs were found in addition on the precursor.

Bacillus cereusisolated from the larvae of Myrmeleon bore was found to secrete proteins that paralyze and kill German cockroaches, Blattela germanica, when injected. One of these active proteins was purified from the culture broth ofB.cereususing anion-exchange and gel-filtration chro-matography. The purified toxin, with a molecular mass of 34 kDa, was identified as sphingomyelinase C (EC3.1.4.12) on the basis of its N-terminal and internal amino-acid sequences. A recombinant sphingomyelinase C expressed in Escherichia coliwas as potent as the native protein in killing the cockroaches....

During vitellogenesis, one of the most tightly regulated processes in ovipar-ous reproduction, vitellogenins are incorporated into the oocyte through vitellogenin receptor (VgR)-mediated endocytosis. In this paper, we report the cloning of the VgR cDNA from Blattella germanica, as well as the first functional analysis of VgR following an RNA interference (RNAi) approach.

A highly active glutathioneS-transferase was purified from adult German cockroaches,Blattella germanica. The purified enzyme appeared as a single band of 24 kDa by SDS⁄PAGE, and had a different electrophoretic mobil-ity than, a previously identified Sigma class glutathione S-transferase (Bla g 5).
