Key facts
Host species:Rabbit,
Clonality:Monoclonal,
Clone number:EPR1574,
Isotype:IgG,
Carrier free:No,
Reacts with:Human,
Applications:IHC-P, WB, IP, DotSee reactivity dataSee the reactivity data table below for information on validated species and application combinations.,
Immunogen:The exact immunogen used to generate this antibody is proprietary information.,
Specificity:This antibody only detects Stathmin 1 phosphorylated on Serine 62. The antibody immunogen shares 86% homology with Stathmin-2, therefore it is possible that the antibody will cross-react with Stathmin-2 when phosphorylated at serine 97. This has not been assessed experimentally.

Stathmin 1 also known as Oncoprotein 18 (Op18) is a cytoplasmic phosphoprotein weighing approximately 19 kDa. It functions primarily by regulating microtubule dynamics; it destabilizes microtubules and promotes depolymerization. Stathmin 1 achieves this by binding to tubulin heterodimers preventing their polymerization into microtubules. This protein is widely expressed in neurons immune cells and various cancer cell lines indicating its significant role in cellular processes.
Biological function summary
Stathmin 1 is important in cell cycle regulation and cell signaling. It does not operate as part of a larger protein complex but rather exerts its effects directly on microtubules. By overriding the stabilization of microtubules it ensures proper mitotic spindle function. This action is especially significant during the G2/M transition and mitosis contributing to the precise segregation of chromosomes.
Pathways
The regulation of microtubule dynamics by Stathmin 1 plays an important role in cell division and neuronal development. It is involved in the PI3K/AKT signaling pathway which ensures cell survival and proliferation. Stathmin 1 interacts with other regulatory proteins such as Tau which stabilizes microtubules offering a balance between dynamic instability and stabilization. This interaction highlights its involvement in cytoskeletal reorganization essential for both cancer progression and neuronal function.
The altered expression of Stathmin 1 is often associated with various cancers including breast and ovarian cancers. Overexpression leads to enhanced tumor growth and metastasis. It also plays a role in neurological disorders by affecting neuronal microtubules making it of particular interest in research on neurodegenerative diseases like Alzheimer's. Its interaction with proteins like Tau in the brain further connects it to these disorders as both are involved in microtubule modulation important for maintaining cell structure and function.
