Superficially wild type on plates. Slight (<10%), but significant, expansion of synaptic vesicles from the synaptic region of the DA9 motor neuron into the flanking asynaptic regions. Synaptic vesicles also showed a slight but significant accumulation in rimb-1 mutant dendrites in the DA9 motor neuron (192 +/- 32% compared to wild type; N=15; P=.015). The sequence GC TAG C TAA A TGA (3 successive stop codons in different reading frames) was inserted after codon 16 of the rimb-1 gene; described in Edwards SL, et al. (manuscript in revision). "Sentryn Acts with a Subset of Active Zone Proteins in the Guided Transport and Capture of Synaptic Vesicles in Caenorhabditis elegans."

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.

Superficially wild-type. Note that double homozygous mutants of pkc-3(it309) with par-2(it315) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tag on pkc-3 shows no effect in an otherwise wild-type background, it does seem to somewhat compromise the activity of the protein it tags. Made in N2 background.

par-2(it315) exhibits a weak maternal effect sterility, suggesting that the tag reduces the protein activity. Note, however, that double homozygous mutants of it315 with pkc-3(it309) or par-6(it310) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tags on pkc-3 and par-6 show no effect in an otherwise wild-type background, they do seem to somewhat compromise the activity of the proteins they tag. Made in N2 background.
