JH3247 C. elegans meg-4(ax2080) X. Show Description
C-terminal FLAG insertion in endogenous meg-4 locus. Reference: Wang JT, et al. eLife 2014;3:e04591.
JH3248 C. elegans meg-4(ax2081) X. Show Description
Deletion removing 733 base pairs upstream of start and the first 2565 bases of the endogenous meg-4 locus. Reference: Wang JT, et al. eLife 2014;3:e04591.
JH3475 C. elegans meg-3(ax3055) meg-4(ax3052) X. Show Description
Embryonic P granules not segregated, 30% maternal effect sterility on average, RNAi insensitivity. meg-3(ax3055) and meg-4(ax3052) are precise deletions of the entire coding sequence made by CRISPR/Cas9, designed to be cut again to make insertions at the endogenous locus.

JH3477 C. elegans meg-3(ax3051[meg-3::OLLAS]) meg-4(ax3052) X. Show Description
P granule size reduced, detection of MEG-3 by anti-OLLAS antibody. References: Smith, J. et al. Elife. 2016 Dec 3;5:e21337. doi: 10.7554/eLife.21337. PMID: 27914198 Schmidt H, bioRxiv 2020.10.15.340570 (2020) doi:10.1101/2020.10.15.340570.
JH3553 C. elegans meg-3(ax4503[del(1-544)::OLLAS]) meg-4(ax4504) X. Show Description
Description: 20% maternal effect sterility on average, RNAi insensitivity, MEG-3 does not form cytoplasmic gradient. meg-3(ax4503) is an in-frame deletion in the endogenous meg-3 locus removing amino acids (1-544); MEG-3 does not form a cytoplasmic gradient but does still form granules in early embryos and co-localizes with PGL-3.

JH3861 C. elegans meg-3(ax4502[meg-3(F705A,Y708A,Y713A, N725A)::OLLAS]) meg-4(ax3052) X. Show Description
20% Maternal effect sterility on average, embryonic P granule defect, RNAi insensitivity. Engineered mutations in the endogenous meg-3 locus disrupt the binding and localization of PGL proteins to P granules in the early embryo while MEG-3 itself is still forms an asymmetric cytoplasmic gradient and granules.
