Knock-in into previously modified unc-119(ox819) endogenous locus. Cas9 insertion marked with myo-2p::cyOFP (cyan-excitable Orange Fluorescent Protein), a long-Stokes-shift fluorescent protein that is spectrally separable from common green and red fluorophores.

KG5148 C. elegans unc-104(ce833[5xMyc::AID::unc-104+sup-1(e995)]) II. Show Description
The Auxin Inducible Degron (AID) flanked by a 5X Myc/spacer tag on left and a single spacer on the right is fused to the N-terminus of the unc-104 gene. Allows conditional degradation of UNC-104 protein when combined with tissue specific expression of TIR1 in the presence of 1 mM Auxin in plate media. Note: KG5148 does not express TIR1. On standard plates: wild type growth, appearance, and locomotion rate. For animals expressing a TIR1 transgene in the nervous system: Animals that hatch and develop on 1 mM Auxin plates generally remain tightly coiled near the location of hatching and exhibit slow growth (up to 7 days to reach adulthood, with 98% reaching adulthood by 7 days). Adults placed on Auxin abruptly lose about 75% of their locomotion function between 6 and 12 hours after plating. The remaining locomotion function is lost gradually between 12 and 52 hours.

Wild-type to mildly long phenotype, sometimes a bit Unc. Segregates wild-type, Dpy-18 (hT2[dpy-18 bli-4] homozygotes), hDf10 dpy-5 unc-29 homozygotes (probably dead eggs) and large numbers of aneuploids (dead eggs). dpy-18(h662) completely suppresses bli-4(e937), is only very mildly Dpy, and has a distinctive dark body and large clear vulval region as a young adult, before becoming gravid. Do not passage: hT2 homozygotes seem somewhat healthier than the het, and will overgrow the plate. Pick longish wild-types and check for correct segregation of progeny to maintain.
