BU7222 C. elegans pat-3(st564) III; kqEx73. Show Description
kqEx73 [pat-3(sp) + rab-3::RFP + cki-1::GFP]. Pick RFP+ to maintain. kqEx73 carries a form of pat-3 gene with splicing defects; rescues pat-3 null allele. pat-3(sp) is a frameshift mutation in the splice acceptor region (ag to aa) that abolishes conserved interaction domains such as the NPxY motifs and creates a splice variant with an extra 19 amino acids. The pat-3(sp) animals not only produce mutant pat-3, but also express the regular splice form due to utilization of an unusual splice acceptor. Abnormal Distal Tip Cell migration and pat-3 gene splicing (intron 7) defects. Reference: Kihira S, et al. PLoS One. 2012;7(8):e42425.
