    Protocol

    Specificity / Sensitivity

    Phospho-Stathmin (Ser38) Antibody detects endogenous levels of stathmin protein only when phosphorylated at Ser38.

    Species Reactivity:

    Human, Mouse, Rat

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser38 of human stathmin. Antibodies are purified using protein A and peptide affinity chromatography.

    Background

    Stathmin is a ubiquitously expressed microtubule destabilizing phosphoprotein that is upregulated in a number of cancers. The amino terminus of the protein contains multiple phosphorylation sites and is involved in the promotion of tubulin filament depolymerization. Phosphorylation at these sites inactivates the protein and stabilizes microtubules. Ser16 phosphorylation by CaM kinases II and IV (1,2) increases during G2/M-phase and is involved in mitotic spindle regulation (3,4). Ser38 is a target for cdc2 kinase (5) and TNF-induced cell death gives rise to reactive oxygen intermediates leading to hyperphosphorylation of stathmin (6). EGF receptor activation of Rac and cdc42 also increases phosphorylation of stathmin on Ser16 and Ser38 (7). Other closely related family members are neuronally expressed and include SCG10, SCLIP, RB3 and its splice variants RB3' and RB3''. Stathmin and SCG10 have been shown to play roles in neuronal-like development in PC-12 cells (8).
