Abstract: The recent cloning and sequencing of several insect vitellogenins (Vg), the major yolk protein precursor of most oviparous animals, and the mosquito Vg receptor (VgR) has brought the study of insect vitellogenesis to a new plane. Insect Vgs are homologous to nematode and vertebrate Vgs. All but one of the insect Vgs for which we know the primary structure are cleaved into two subunits at a site [(R/K)X(R/K)R or RXXR with an adjacent beta-turn] recognized by subtilisin-like proprotein convertases. In four of th…
