CC -!- FUNCTION: Regulatory component of the inositol phosphorylceramide (ICP)
CC synthase which catalyzes the addition of a phosphorylinositol group
CC onto ceramide to form inositol phosphorylceramide, an essential step in
CC sphingolipid biosynthesis. Helps the medial Golgi localization of IPC
CC synthase in a COPI vesicle-dependent manner (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Component of the inositol phosphorylceramide synthase complex
CC composed of at least aur1 and kei1. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000269|PubMed:16823372}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:16823372}.
CC -!- SIMILARITY: Belongs to the KEI1 family. {ECO:0000305}.
