CC -!- FUNCTION: Regulator of microtubule dynamics that plays a key role in
CC myelination by promoting elongation of the myelin sheath
CC (PubMed:31522887). Acts as a microtubule nucleation factor in
CC oligodendrocytes: specifically localizes to the postsynaptic Golgi
CC apparatus region, also named Golgi outpost, and promotes microtubule
CC nucleation, an important step for elongation of the myelin sheath
CC (PubMed:31522887, PubMed:33831707). Required for both uniform polarized
CC growth of distal microtubules as well as directing the branching of
CC proximal processes (PubMed:31522887). Shows magnesium-dependent GTPase
CC activity; the role of the GTPase activity is unclear (PubMed:21995432,
CC PubMed:21316364). In addition to microtubule nucleation activity, also
CC involved in microtubule bundling and stabilization of existing
CC microtubules, thereby maintaining the integrity of the microtubule
CC network (PubMed:17105200, PubMed:17693641, PubMed:18028908,
CC PubMed:26289831). Regulates microtubule dynamics by promoting tubulin
CC acetylation: acts by inhibiting the tubulin deacetylase activity of
CC HDAC6 (PubMed:20308065, PubMed:23093407). Also regulates cell
CC migration: phosphorylation by ROCK1 inhibits interaction with HDAC6,
CC resulting in decreased acetylation of tubulin and increased cell
CC motility (PubMed:23093407). Plays a role in cell proliferation by
CC regulating the G1/S-phase transition (PubMed:23355470). Involved in
CC astral microtubule organization and mitotic spindle orientation during
CC early stage of mitosis; this process is regulated by phosphorylation by
CC LIMK2 (PubMed:22328514). {ECO:0000269|PubMed:17105200,
