ZM10113 C. elegans twk-40(bln282[twk-40::TagRFP::ZF]) III; hpIs727. Show Description
hpIs727 [rig-3p::zif-1::sl2::RFP + ttx-3p::GFP]. twk-40(bln282) is a CRISPR generated tagged allele of endogenous twk-40 locus inserting TagRFP and a ZIF-1 directed degron to the endogenous TWK-40, allowing visualization of endogenous protein expression and localization as well as targeted degradation. The presence of hpIs727 in the background leads to specific degradation of TWK-40 from AVA, causing loopy forward and reversal movement compared to twk-40(bln282) alone.
ZM10206 C. elegans hpIs758. Show Description
hpIs758 [rig-3p::LoxP::eBFP::LoxP::Chrimson::wCherry + twk-40(s)p::Cre + myo-2p::wCherry]. Pick animals with red fluorescence to maintain. Weak myo-2 and AVA Cherry expression. hpIs758 is a spontaneous insertion of hpEx4080. Reference: Lu Y, et al. 2022. Current Biology (In Press).

Red fluorescence in AVA. twk-40(hp834) is a loss-of-function allele. twk-40(hp834) itself is highly loopy and a weak backward coiler. The presence of hpIs814 in the background reduces body bending and speed compared to twk-40(hp834) alone.

OH10723 C. elegans pha-1(e2123) III; otEx4805. Show Description
otEx4805 [twk-40p(2.5kb promoter)::DsRed2 + pha-1(+)]. Maintain at 25C. Reference: Kratsios P, et al. Nat Neurosci. 2011 Nov 27. doi: 10.1038/nn.2989.
ZM10538 C. elegans hpIs774; hpEx4081. Show Description
hpIs774 [twk-40p(short)::GCaMP6s::mNeptune]. hpEx4081 [rig-3p::LoxP::eBFP::Stop::LoxP::gtACR2::wCherry + twk-40p(short)::Cre + myo-2p::RFP]. Pick RFP+ (pharynx) to maintain. Transgenic animals are GFP and RFP positive in multiple neurons in the head, but strong RFP signals in AVA neurite. Superficially wild type. Activation of gtACR2 decreases AVA and AVB’s calcium signals. hpEx4081 can be maintained by picking animals with weak pharyngeal RFP signals (seems to be a common artifact of the Cre-LoxP system).
