WormBase Gene ID  ? WBGene00021058 Gene Name  vps-18
Sequence Name  ? W06B4.3 Brief Description  vps-18 encodes the C. elegans ortholog of the vacuolar sorting protein VPS18/Vps18p; vps-18 activity is essential for formation of early endosomes, late endosomes, and lysosomes and thus, for endosome-lysosome trafficking and lysosomal protein degradation; vps-18 thus also plays a role in phagosome maturation during apoptotic cell degradation.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable protein-macromolecule adaptor activity. Involved in endosome organization and phagosome-lysosome fusion involved in apoptotic cell clearance. Located in cytoplasm. Expressed in body wall musculature; coelomocyte; hermaphrodite gonad; hypodermis; and intestine. Is an ortholog of human VPS18 (VPS18 core subunit of CORVET and HOPS complexes).
Biotype  SO:0001217 Genetic Position  II :-4.35664 ±0.008885

  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing. [cgc5767]:expression_class_SM

  Maternal class (M): genes that are called present in at least one of the three PC6 replicates. A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression.

In early larvae, VPS-18::GFP was mainly seen in hypodermal cells, seam cells and some body-wall muscle cells. In adult hermaphrodite, VPS-18::GFP was detected in coelomocytes. VPS-18::GFP signal was also present in gonadal sheath cells. In addition, VPS-18::GFP was expressed in intestine and spermatheca. cytoplasmic
