Commun. 3:876-876(2012). CC -!- FUNCTION: Regulator of microtubule stability. When phosphorylated by CC MAPK8, stabilizes microtubules and consequently controls neurite length CC in cortical neurons. In the developing brain, negatively regulates the CC rate of exit from multipolar stage and retards radial migration from CC the ventricular zone. {ECO:0000269|PubMed:16618812, CC ECO:0000269|PubMed:21297631, ECO:0000269|PubMed:9012855}. CC -!- SUBUNIT: Interacts with ITM2C (By similarity). Interacts with MAPK8. CC Interacts with KIFBP (By similarity). Interacts (via the N-terminal CC region) with CIB1 (via C-terminal region); the interaction is direct, CC occurs in a calcium-dependent manner and attenuates the neurite CC outgrowth inhibition of STMN2 (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, perinuclear region. Cell CC projection, growth cone. Cell projection, axon. Membrane {ECO:0000305}; CC Peripheral membrane protein {ECO:0000305}; Cytoplasmic side CC {ECO:0000305}. Golgi apparatus. Endosome. Cell projection, CC lamellipodium {ECO:0000250}. Note=Colocalized with CIB1 in the cell CC body, neuritis and growth cones of neurons. Colocalized with CIB1 to CC the leading edge of lamellipodia (By similarity). Associated with CC punctate structures in the perinuclear cytoplasm, axons, and growth CC cones of developing neurons. Exists in both soluble and membrane-bound CC forms. Colocalized with CIB1 in neurites of developing hippocampal CC primary neurons. {ECO:0000250}. CC -!- TISSUE SPECIFICITY: Expressed in neurons (at protein level). Present in CC growth cones and abundant in developing neurons. CC {ECO:0000269|PubMed:21215777}. CC -!- DEVELOPMENTAL STAGE: In the developing cerebellum, maximal levels occur CC at postnatal day 7 and correlate with the onset of neuronal CC differentiation. CC -!- INDUCTION: By nerve growth factor. CC -!- PTM: Sumoylated. {ECO:0000250}. CC -!- PTM: Phosphorylated by MAPK9 and MAPK10 in the developing brain cortex CC (By similarity). Phosphorylated mostly by MAPK8. {ECO:0000250, CC ECO:0000269|PubMed:16618812}. CC -!- PTM: N-terminal palmitoylation promotes specific anchoring to the CC cytosolic leaflet of Golgi membranes and subsequent vesicular CC trafficking along dendrites and axons. Neuronal Stathmins are CC substrates for palmitoyltransferases ZDHHC3, ZDHHC7 and ZDHHC15 (By CC similarity). {ECO:0000250}. CC -!- SIMILARITY: Belongs to the stathmin family. {ECO:0000305}.
