[C.elegansII] NMK. pes-6:lacZ expressed throughout H-shaped excretory cell, also in nuclei of lateral hypodermis. Clone UL#64A1, YAC 55E1. [Young and Hope 1993; UL]
vha-8 encodes an ortholog of subunit E of the cytoplasmic (V1) domain ofvacuolar proton-translocating ATPase (V-ATPase); VHA-8 is a predictedcytosolic stator (stalk) component; VHA-8 is required for embryonic andlarval viability, for ovulation, and for receptor-mediated endocytosisof yolk protein; VHA-8 is highly expressed in the cytoplasm of excretorycanals throughout development, and in the stacked apical plasma membranesheets of syncytial hypodermal cells; general levels of VHA-8 proteinare very low in embryos but increase strongly after hatching; vha-8mutants show necrotic cell death in hypodermis and intestine,paralleling the role of VHA-12 and other V-ATPase subunits in neuronalnecrosis; VHA-8 is dispensable for alae formation, like the V1 subunitVHA-13, but not like the V0 subunits VHA-1 and VHA-4.
Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Located in apical plasma membrane and cytoplasm. Expressed in head; hypodermis; and intestine. Human ortholog(s) of this gene implicated in autosomal recessive cutis laxa type IIC. Is an ortholog of human ATP6V1E2 (ATPase H+ transporting V1 subunit E2).
pes-6 was incorrectly connected to C17H12.4 [030416 ck1]
The pes-6 was merged with vha-8 following advice from the CGC. pes-6 is now an other name of vha-8 [krb 030512]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
