Given that each and every gene encodes a membrane protein expressed inside Z1 and Z4, one particular easy possibility would be that one of many proteins acts to recruit the other for the plasma membrane. We tested this possibility by examining the expression/localization of GEM1::GFP inside a catp6(0) background, and CATP6::GFP in a gem1(0) background. We discovered that GEM1::GFP linked usually with all the plasma membrane of Z1 and Z4 inside a catp6(0) background (Figure 11), as did CATP6::GFP in a gem1(0) background (Figure 12). Hence, neither protein is strictly dependent on the activity of the other in terms of expression or subcellular localization. However, due to the fact each and every fusion construct is present on an extrachromosomal array, we can not totally exclude the possibility that typical regulatory constraints may possibly be overwhelmed by overexpression in the transgene. Furthermore, higher resolution imaging will be necessary to detect subtle adjustments in subcellular protein localization.connected using the plasma membrane of your somatic gonad precursor cells, Z1 and Z4 (Figure 7).CATP6 expression inside Z1 and Z4 rescues gonadogenesisSince gem1 and catp6 interact genetically, the simplest scenario will be that each genes act within the identical cell form, i.e, Z1 and Z4. Indeed, we located that when we utilised the ehn3 promoter to drive catp6::gfp expression within Z1 and Z4 we had been in a position to rescue the catp6(0) phenotype (Table 3). The ehn3 promoter also drives expression within a small quantity of neurons inside the head and tail region (Figure eight), so it remained formally possible that catp6 functions inside these cells, instead of the somatic gonad precursors. Consequently, we also tested no matter if driving catp6 using the panneuronal unc119 promoter could rescue catp6(0). Though we did observe widespread expression of catp6::gfp within the nervous method (Figure 9), this didn’t lead to rescue from the catp6(0) phenotype (Table three). Similarly, when we employed the myo3 promoter to drive catp6::gfp in physique muscles we didn’t observe any rescuing activity (Table 3), regardless of successful expression (Figure ten).Effects of overexpression of CATP6 and GEMUsing the transgenic strains described above, we tested no matter whether expression of CATP6::GFP could bypass the requirement for gem1().
