A mutation in the Bombyx mori BmSPI51 gene results in alterations protein abundance in cocoon and unveils compensatory mechanism of silk gland proteinase inhibitors.

Abstract excerpt

Proteinase inhibitors constitute a significant component of Lepidoptera cocoon. BmSPI51 is the most abundant protease inhibitors in silkworm cocoons. In this study, we aimed to elucidate the biological function of BmSPI51 in both the silkworm silk gland and cocoon formation. To achieve this, we utilized CRISPR/Cas9 gene editing to target the BmSPI51 gene, resulting in premature termination of translation at the...
