CC -!- FUNCTION: Secreted glycoprotein regulating the activation of CC different signaling pathways in adjacent cells to control CC different processes including cell adhesion, cell-matrix adhesion, CC cytoskeleton organization and cell migration. Promotes substrate CC adhesion, spreading and formation of focal contacts. Negatively CC regulates cell-matrix adhesion and stress fiber assembly through CC Rho protein signal transduction. Modulates the organization of CC actin cytoskeleton by stimulating the formation of stress fibers CC through interactions with components of Wnt signaling pathways. CC Promotes cell migration through activation of PTK2 and the CC downstream phosphatidylinositol 3-kinase signaling. Plays a role CC in bone formation and promotes osteoblast differentiation in a CC dose-dependent manner through mitogen-activated protein kinase CC signaling. Mediates myelination in the peripheral nervous system CC through ERBB2/ERBB3 signaling. Plays a role as a regulator of CC muscle hypertrophy through the components of dystrophin-associated CC protein complex. Involved in positive regulation of mitochondrial CC depolarization. Plays a role in neurite outgrowth. May participate CC in the obstruction of fluid outflow in the trabecular meshwork (By CC similarity). CC -!- SUBUNIT: Homodimer (via N-terminus). Interacts with OLFM3, FN1, CC NRCAM, GLDN and NFASC. Interacts (via N-terminus) with MYL2. CC Interacts with SFRP1, FRZB, FZD7, FZD10, FZD1 and WIF1; regulates CC Wnt signaling. Interacts with SNTA1; regulates muscle hypertrophy. CC Interacts with ERBB2 and ERBB3; acivates ERBB2-ERBB3 signaling CC pathway. Interacts with SNCG; affects its secretion and its CC aggegation (By similarity). CC -!- SUBCELLULAR LOCATION: Secreted (By similarity). Golgi apparatus CC (By similarity). Cytoplasmic vesicle (By similarity). Secreted, CC extracellular space (By similarity). Secreted, extracellular CC space, extracellular matrix (By similarity). Secreted, exosome (By CC similarity). Mitochondrion (By similarity). Mitochondrion CC intermembrane space (By similarity). Mitochondrion inner membrane CC (By similarity). Mitochondrion outer membrane (By similarity). CC Rough endoplasmic reticulum (By similarity). Cell projection (By CC similarity). Cell projection, cilium (By similarity). Note=Located CC preferentially in the ciliary rootlet and basal body of the CC connecting cilium of photoreceptor cells, and in the rough CC endoplasmic reticulum. It is only imported to mitochondria in the CC trabecular meshwork. Localizes to the Golgi apparatus in Schlemm's CC canal endothelial cells. Appears in the extracellular space of CC trabecular meshwork cells by an unconventional mechanism, likely CC associated with exosome-like vesicles. Localizes in trabecular CC meshwork extracellular matrix (By similarity). CC -!- SUBCELLULAR LOCATION: Myocilin, C-terminal fragment: Secreted (By CC similarity). CC -!- SUBCELLULAR LOCATION: Myocilin, N-terminal fragment: Endoplasmic CC reticulum. Note=Remains retained in the endoplasmic reticulum (By CC similarity). CC -!- TISSUE SPECIFICITY: Expressed in optic nerve head, ciliary body CC and retina. CC -!- PTM: Palmitoylated (By similarity). CC -!- PTM: Undergoes a calcium-dependent proteolytic cleavage at Arg-212 CC by CAPN2 in the endoplasmic reticulum. The result is the CC production of two fragments, one of 35 kDa containing the C- CC terminal olfactomedin-like domain, and another of 20 kDa CC containing the N-terminal leucine zipper-like domain (By CC similarity). CC -!- SIMILARITY: Contains 1 olfactomedin-like domain.
