E03H4.8 encodes one of two C. elegans proteins with similarity to the beta' coat protein of the COPI vesicular coat; by homology, E03H4.8 is required for retrograde trafficking from the cis-Golgi to the endoplasmic reticulum and trafficking within the Golgi stack; in C. elegans, RNAi experiments indicate that E03H4.8 is required for proper germ cell development and reproduction; about 10% to 20% of E03H4.8 transcripts are RNA edited to change A to G resulting in a change to residue 331 from an S to a G.
Predicted to enable structural molecule activity. Predicted to be involved in intracellular protein transport and vesicle-mediated transport. Predicted to be part of membrane coat.
