CC   -!- FUNCTION: May play a role in neural plasticity. May be involved during
CC       axon regeneration.
CC   -!- SUBUNIT: Forms disulfide-linked dimers.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: EPDs are synthesized in the meninx and secreted in
CC       the cerebrospinal fluid.
CC   -!- PTM: Different glycosylation variants are known as EPD-beta and EPD-
CC       gamma.
CC   -!- PTM: Binds calcium through the terminal sialic acids.
CC   -!- SIMILARITY: Belongs to the ependymin family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAA49165.1; Type=Erroneous initiation; Evidence={ECO:0000305};
