CC -!- FUNCTION: Ligand for NRCAM and NFASC/neurofascin that plays a role in
CC the formation and maintenance of the nodes of Ranvier on myelinated
CC axons. Mediates interaction between Schwann cell microvilli and axons
CC via its interactions with NRCAM and NFASC (PubMed:16039564). Nodes of
CC Ranvier contain clustered sodium channels that are crucial for the
CC saltatory propagation of action potentials along myelinated axons.
CC During development, nodes of Ranvier are formed by the fusion of two
CC heminodes. Required for normal clustering of sodium channels at
CC heminodes; not required for the formation of mature nodes with normal
CC sodium channel clusters. Required, together with NRCAM, for maintaining
CC NFASC and sodium channel clusters at mature nodes of Ranvier (By
CC similarity). {ECO:0000250|UniProtKB:Q8BMF8,
CC ECO:0000269|PubMed:16039564}.
CC -!- SUBUNIT: Homotrimer (via collagen-like domains) (PubMed:17485493)
CC (Probable). Interacts with NRCAM (PubMed:16039564, PubMed:22009740).
CC Interacts with NFASC/neurofascin (PubMed:16039564, PubMed:17485493,
CC PubMed:22009740). Interaction with glial NRCAM enhances interaction
CC with axonal NFASC. Interacts with MYOC (By similarity).

CC (PubMed:16039564, PubMed:22009740). Detected at immature heminodes
CC (PubMed:22009740). {ECO:0000269|PubMed:16039564,

CC -!- SUBCELLULAR LOCATION: [Gliomedin shedded ectodomain]: Secreted
CC {ECO:0000269|PubMed:17485493}. Secreted, extracellular space,
CC extracellular matrix {ECO:0000269|PubMed:17485493}. Note=Proteolytic
CC processing gives rise to a soluble extracellular domain that is
CC secreted. The gliomedin shedded ectodomain localizes to the nodes of
CC Ranvier. {ECO:0000269|PubMed:17485493}.
CC -!- TISSUE SPECIFICITY: Detected in Schwann cells (at protein level).
CC {ECO:0000269|PubMed:17485493}.
CC -!- DEVELOPMENTAL STAGE: Expression increases in myelinating Schwann cells
CC during the initial period of active myelination.
CC {ECO:0000269|PubMed:16039564}.
CC -!- DOMAIN: The olfactomedin-like domain mediates NFASC/neurofascin and
CC NRCAM binding. {ECO:0000250|UniProtKB:Q8BMF8}.
CC -!- PTM: N-glycosylated. {ECO:0000269|PubMed:17485493}.
CC -!- PTM: Proteolytic proccessing by a furin-like protease causes shedding
CC of the ectodomain (PubMed:17485493). Further cleavage by BMP1 releases
CC the olfactomedin-like domain. {ECO:0000250|UniProtKB:Q8BMF8,
CC ECO:0000269|PubMed:17485493}.
