Strains carrying this gene

Strain Genotype Description
AN170 aff-1(ty4) unc-4(e120)/mnC1 [dpy-10(e128) unc-52(e444)] II. Heterozygotes are WT and segregate WT (heterozygotes), Unc-4 worms which are strong Egl (ty4 homozygotes), and paralyzed Dpy Uncs (mnC1 homozygotes).
BP395 hyEx167. hyEx167 [4.5kb aff-1p::GFP transcriptional fusion + rol-6(su1006)]. Shows cytoplasmic GFP expression in embryonic hyp5. In L1 hermaphrodite larva, aff-1::GFP is expressed in pharyngeal muscle 3 and 5, in sheath cells of chemosensory neurons, and in tail neurons. In L3 hermaphrodites, the transgene is expressed in the anchor cell; this expression proceeds in L4 along with expression in the utse cells, the seam cells and cells of vulval rings A and D. In adults, aff-1::GFP is expressed in the sheath cells of chemosensory neurons and in head interneurons, uterus toroids 2 and 4, in the vulva VulD, utse, and seam cells. Worms of hyEx167 are slightly Egl. Maintain by picking Rollers.
BP600 aff-1(tm2214) II. A 1.2 kb deletion in aff-1 (C44B7.3) which introduce stop codon after alanine 47. AFF-1 is a type I membrane protein necessary and sufficient for specific cell fusion events during embryonic and larval development. Temperature sensitivity was not detected. At 20° the fusion of hyp5 in the embryo does not occur as well as anchor cell (AC) fusion, vulval cells fusion of the A and D rings and the terminal fusion between the seam cells late in L4. 6% L1 rod-like lethal and 0% embryonic lethal. Adults are completely Egl, and partially Unc, Pvl. In addition, only 2% of AC in the mutant worms undergo fusion. These animals give very low brood size (16 progeny per worm) and 3.4% of the worms are sterile. This strain gives very small brood size and hence grows slowly. Originally from Shohei Mitani, Tokyo Women's Medical College, Tokyo, Japan.
BP601 aff-1(tm2214)/mIn1 [dpy-10(e128) mIs14] II. Heterozygotes are WT with major GFP signal in pharynx. Segregates WT GFP+, Dpy GFP+ (mIn1 homozygotes) and few GFP- tm2214 homozygotes animals which give very small brood size and hence can only be slowly propagated (see BP600 for detailed description for homozygote tm2214 phenotypes). Pick WT dim GFP non Dpy animals and check for correct segregation of progeny to maintain.
BP610 eff-1(ok1021) aff-1(tm2214)/mIn1 [mIs14 dpy-10(e128)] II. Heterozygotes are WT with relatively dim pharyngeal GFP signal. Segregates Dpy with bright GFP (mIn1 homozygotes). Segregates very few escapers that are non-GFP (ok1021 tm2214 homozygotes).
