Maternal ATP-binding protein that may have multiple functions during development, one of which may be associated with the development and maintenance of the central nervous system. Cytoplasmic (following oocyte maturation), then nuclear (blastula/gastrula stage). In Xenopus oocyte, in the central nervous system cells of tadpoles and adult frogs, and transiently in epithelial cells of stomach and gut of tadpoles. Highly expressed in kidney. Neurula stage and in adult brain. The polybasic C-terminal domain is not required for membrane localization. May be phosphorylated during oocyte maturation. Palmitoylated on Cys-585 and Cys-587 and prenylated on Cys-588; which is required for membrane association. Belongs to the paralemmin family.
