CC   -!- FUNCTION: Eca and bai are essential, though not redundant, for
CC       dorsoventral patterning of the embryo. Specifically required during
CC       early embryogenesis for the activity of maternal tkv, while the zygotic
CC       tkv is not affected. Involved in Golgi organization (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000255};
CC       Single-pass type I membrane protein {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the EMP24/GP25L family. {ECO:0000255}.
