In vertebrates, 10 Ca(2+) channel genes, grouped in 3 families (CaV1, CaV2 and CaV3), have been described and characterized. Insects possess only one member of each family. These genes have been isolated in a limited number of species and very few have been characterized although, in addition to their crucial role, they may represent a collateral target for neurotoxic insecticides. We have isolated the 3 genes coding for the 3 Ca(2+) channels expressed in Apis mellifera. This work provides the first detailed characterization of the honeybee T-type CaV3 Ca(2+) channel and demonstrates the low toxicity of inhibiting this channel. Comparing Ca(2+) currents recorded in bee neurons and myocytes with Ca(2+) currents recorded in Xenopus oocytes expressing the honeybee CaV3 gene suggests native expression in bee muscle cells only. High-voltage activated Ca(2+) channels could be recorded in the somata of different cultured bee neurons. These functional data were confirmed by in situ hybridization, immunolocalization and in vivo analysis of the effects of a CaV3 inhibitor. The biophysical and pharmacological characterization and the tissue distribution of CaV3 suggest a role in honeybee muscle function. %G English %2 https://hal.science/hal-01595255/document %2 https://hal.science/hal-01595255/file/Honey._%7B9F01FB34-35C6-4299-A69F-4CEBAD5AF169%7D.pdf %L hal-01595255 %U https://hal.science/hal-01595255 %~ IRD %~ UNIV-AVIGNON %~ UNIV-TLSE2 %~ UNIV-TLSE3 %~ CNRS %~ UNIV-ANGERS %~ UNIV-PSUD %~ ENSC-MONTPELLIER %~ INRA %~ IBMM %~ CRCA %~ INC-CNRS %~ UNIV-PARIS-SACLAY %~ AGREENIUM %~ UNIV-PSUD-SACLAY %~ CHIMIE %~ UNIV-MONTPELLIER %~ SIFCIR %~ INRAE %~ TEST-HALCNRS %~ EGCE %~ AE %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ UM-2015-2021 %~ TEST3-HALCNRS %~ TEST4-HALCNRS %~ INRAEPACA %~ TEST5-HALCNRS
