UniProt names and subcellular location Protein identifiers Protein names Subcellular locations Stathmin-2
Superior cervical ganglion-10 protein
Source Identifiers UniProt gene names Stmn2, Scg10, Scgn10 IPI ID IPI00326596, IPI00190960 Refseq protein ID NP_445892.1 RGD ID 68947 Ensembl protein ENSRNOP00000015720 Ensembl gene ENSRNOG00000011705 UniProt AC P21818 UniProt ID STMN2_RAT UniProt secondary AC Q9ERH2 Protein length Isoform 1 (main): 179 aa Known functions (from UniProt) N-terminal palmitoylation promotes specific anchoring to the cytosolic leaflet of Golgi membranes and subsequent vesicular trafficking along dendrites and axons. Neuronal Stathmins are substrates for palmitoyltransferases ZDHHC3, ZDHHC7 and ZDHHC15 (By similarity). Belongs to the stathmin family. Contains 1 SLD (stathmin-like) domain. Regulator of microtubule stability. When phosphorylated by MAPK8, stabilizes microtubules and consequently controls neurite length in cortical neurons. In the developing brain, negatively regulates the rate of exit from multipolar stage and retards radial migration from the ventricular zone. Interacts with ITM2C (By similarity). Interacts with MAPK8. Interacts with KIF1BP (By similarity). Interacts (via the N-terminal region) with CIB1 (via C-terminal region); the interaction is direct, occurs in a calcium-dependent manner and attenuates the neurite outgrowth inhibition of STMN2 (By similarity). Colocalized with CIB1 in the cell body, neuritis and growth cones of neurons. Colocalized with CIB1 to the leading edge of lamellipodia (By similarity). Associated with punctate structures in the perinuclear cytoplasm, axons, and growth cones of developing neurons. Exists in both soluble and membrane-bound forms. Colocalized with CIB1 in neurites of developing hippocampal primary neurons. Expressed in neurons (at protein level). Present in growth cones and abundant in developing neurons. In the developing cerebellum, maximal levels occur at postnatal day 7 and correlate with the onset of neuronal differentiation. By nerve growth factor. Sumoylated. Pphosphorylated by MAPK9 and MAPK10 in the developing brain cortex (By similarity). Phosphorylated mostly by MAPK8.
