Cevps-27 = C07G1.5 Immunohistochemical analyses with anti-CeVPS-27 antibodies (Figure 2AD,GJ) and observation of CeVPS-27::GFP transgenic worms (Figure 2E,F,K) revealed a similar expression pattern. Picture: Figure 2, Figure 3. Several arguments support the idea that CeVPS-27 localizes to endosomes. First, CeVPS-27-positive vesicles are not lysosomes as revealed by an absence of colocalization of CeVPS-27::GFP with the lysosomal marker lysotracker. Second, CeVPS-27 is localized in vesicles close to the plasma membrane in epithelial cells and in the coelomocytes, which are specialized in endocytosis of fluid and macromolecules from the body cavity. Finally, the inactivation of the homolog of the class E vps-23, which in yeast and mammals results in the formation of enlarged endosomes, induced the production of enlarged CeVPS-27-positive vesicles. Together, these data indicate that CeVPS-27 is localized at the endosomal membrane in C. elegans. |

CeVPS-27 was detected ubiquitously, as early as in the 2-cell embryo and persisted throughout the embryonic and larval development and in adult animals. At mid-embryogenesis, when epithelialization proceeds, CeVPS-27-positive vesicles were preferentially enriched in hypodermal, pharyngeal and intestinal cells. The specificity of the signal was confirmed by its complete disappearance after inactivation of Cevps-27 by RNAi. During larval development and in adults, CeVPS-27 was expressed ubiquitously but remained more abundant in the intestine, the hypodermis, the pharynx and in the adult epithelial tissues; namely the uterus, the vulva, the spermatheca and the gonad. CeVPS-27 could also be found in the excretory canal, and the six scavenger cells called coelomocytes. |
The protein was detected as a punctate pattern in the cytoplasm indicating a vesicular localization. At mid-embryogenesis, when epithelialization proceeds, CeVPS-27-positive vesicles were preferentially enriched in hypodermal, pharyngeal and intestinal cells, where they localized close to the apical membrane as revealed by the apical junction marker AJM-1. Later during morphogenesis, CeVPS-27-positive vesicles became more uniformly localized. Several arguments support the idea that CeVPS-27 localizes to endosomes (see Remark). |

GFP expression was observed in various tissues, including many neurons in the head and tail, head muscles, intestine, phasmid socket cells, spermatheca, and eggs. A weak expression was also observed in the cells of the gonad and vulva. The neurons expressing ser-3 promoter-driven GFP in the tail were identified as PHA, PHB, and PVQ neurons. |

In mated females, extracellular MSP exhibits a graded distribution, with a sharp boundary between the -1 and -2 oocytes. Fluorescence intensity measurements indicate that MSP is localized in a graded manner from the spermatheca to the oocyte. Fluorescence intensity measurements also indicate that there is significant MSP staining over the -2 and -3 oocytes. To pinpoint the localization of MSP at the oocyte cell surface, a 3D confocal analysis of MSP localization was conducted a in mated females using the RME-2 yolk receptor to mark the oocyte plasma membrane and the early endosomal compartments. Three-dimensional image reconstructions of the data indicate that MSP localizes in three regions: (1) in superficial focal planes at the oocyte cell surface with RME-2 just beneath; (2) in the same plane as the RME-2 signal; and (3) within the oocyte beneath the plasma membrane. Using anti-MSP mAbTR-20 and visual inspection, 91% of mated female gonad arms exhibited extracellular MSP localization (n=36), with 39% showing extracellular MSP as far as the most proximal oocyte, and the rest exhibiting extracellular MSP only within the spermatheca. With confocal microscopy, extracellular MSP appeared both punctate and diffuse in the spermatheca, the gonad arm and the uterus. Analysis of 3D data stacks indicated that punctate extracellular MSP was enriched near spermatozoa on the spermathecal walls. The largest puncta were at the diffraction limit of the microscope (0.5 um) and were found nearby spermatozoa. In the proximal gonad arm, MSP was more diffuse and localized in focal plane slices near the oocyte surface. In the uterus, large MSP puncta was observed close to spermatozoa. Diffuse MSP was also observed in extracellular spaces surrounding embryos in the uterus. MSP puncta can be observed near spermatozoa in the uterus and spermatheca using wide-field microscopy, when these regions were less crowded with spermatozoa. |
