As homozygote suppresses blister formation in bli-1(sc73), bli-2(sc768) and bli-6(sc16). WT phenotype. Males sometimes have small blisters above their bursas. Males mate well. See wbg9.1p51.

Homozygous viable. Endogenous erm-1 locus tagged with eGFP and modified to mimic non-phosphorylated ERM-1(T544). Variant affects ERM-1 localization and dynamics. Reduced brood size, increased embryonic and larval lethality. eGFP-tagged ERM-1 is not fully functional: animals have a reduced brood size and incomplete outgrowth of the excretory canal, but show no other developmental or morphological abnormalities. The penetrance of intestinal phenotypes is slightly higher than in untagged T544 mutants, presumably owing to a detrimental influence of the COOH-terminal GFP tag. Reference: Ramalho JJ, et al.

Egg-laying (Egl) defects and subsequent internal hatching of progeny (Bagging) in > 95% of animals. xe11 is a C-to-U point mutation in each of the endogenous let-7 complementary sites, LCS1 and LCS2 [I:C9,335,211T & I:C9,335,260T]. xe11 is a weak gain-of-function allele: mutation of two functionally relevant let-7 binding sites impairs repression by let-7 causing over-expression of LIN-41 in L4 stage animals.
