BmBlimp-1 gene encoding a C2H2 zinc finger protein is required for wing development in the silkworm Bombyx mori.

ABSTRACT: Cys2-His2 zinc finger (C2H2-ZF) proteins represent the most common class of transcription factors. These factors have great potential for the management of developmental progression by regulating the specific spatiotemporal expression of genes. In this study, we cloned one C2H2-ZF protein gene of Bombyx mori, BGIBMGA000319, that is orthologous to B-lymphocyte-induced maturation protein-1 (Blimp-1); we thus named it as Bombyx mori Blimp-1 (BmBlimp-1). In the silkworm, the BmBlimp-1 gene is specifically upregulated during day 2 of the pupal to adult stage and is highly expressed in wing discs on day 3 of the pupa. Knockdown of its expression level in the pupal stage results in a crumpled-winged silkworm moth. Using the predicted DNA-binding se
