Protein

Stathmin-2

Gene

Stmn2

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.3 Publications

Expressioni

Tissue specificityi

Expressed in neurons (at protein level). Present in growth cones and abundant in developing neurons.1 Publication

Developmental stagei

In the developing cerebellum, maximal levels occur at postnatal day 7 and correlate with the onset of neuronal differentiation.

Interactioni

Subunit structurei

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).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
