Description

A sequence cassette comprising stop codons in all three frames and a loxP cassette that contains a Disc\RFP3xP3.cUa marker has been inserted into the endogenous unc-13 locus, replacing 61bp of unc-13 coding exon sequence. The stop codons are inserted immediately following the start codon of the unc-13 B isoform, resulting in a null mutant for this isoform.

      unc-13B.CRISPR homozygotes show neurotransmission defects in the larval muscle 6 NMJ: decreased eEJP amplitude in the third instar (but not second instar) and increased paired-pulse ratio in the second instar (but not third instar).
