Protein Information
Name STMN1
Synonyms C1orf215, LAP18, OP18
Function Involved in the regulation of the microtubule (MT) filament system by destabilizing microtubules. Prevents assembly and promotes disassembly of microtubules. Phosphorylation at Ser- 16 may be required for axon formation during neurogenesis. Involved in the control of the learned and innate fear (By similarity).
Cellular Location Cytoplasm, cytoskeleton.
Tissue Location Ubiquitous. Expression is strongest in fetal and adult brain, spinal cord, and cerebellum, followed by thymus, bone marrow, testis, and fetal liver. Expression is intermediate in colon, ovary, placenta, uterus, and trachea, and is readily detected at substantially lower levels in all other tissues examined. Lowest expression is found in adult liver. Present in much greater abundance in cells from patients with acute leukemia of different subtypes than in normal peripheral blood lymphocytes, non-leukemic proliferating lymphoid cells, bone marrow cells, or cells from patients with chronic lymphoid or myeloid leukemia

Stathmin (oncoprotein 18, op18) is a ubiquitous cytosolic phosphoprotein with various regulatory functions in cell proliferation, differentiation signaling, and activation (1). In particular, stathmin is involved in the regulation of tubulin dynamics through inhibition of microtubule formation and/or microtubule depolymerization. Stathmin interacts with soluble tubulins (alpha,beta-tubulin) resulting in the formation of T2S complex which sequesters free tubulin, impeding tubulin formation (2). Stathmin activity is regulated through phosphorylation at Ser16, Ser25, Ser38 and Ser63 by various protein kinases (e.g. MAP-kinase, p34cdc2 kinase), weakening stathmin's affinity to tubulin (3). A mutation in stathmin can lead to excess build up of mitotic spindle and with possible consequence of unregulated cell cycles seen in cancer cells (4). Stathmin is also known as the generic member of a protein family which includes neural proteins SCG10, SCLIP and RB3/RB3'/RB3. All members in this family exhibit tubulin binding ability.
