Characteristics: This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 18.1 kDa. The protein migrates as 18 kDa under reducing (R) condition (SDS-PAGE). Description: Stathmin (STMN1), a member of the stathmin family, is also known as Leukemia-associated phosphoprotein p18, Oncoprotein 18 (Op18), Phosphoprotein p19 (pp19), Protein Pr22 and pp17, which contains one SLD (stathmin-like) domain. The function of STMN1 as an important regulatory protein of microtubule dynamics has been well-characterized. Stathmin (STMN1) interacts with two molecules of dimeric α,β-tubulin to form a tight ternary complex called the T2S complex.One mole of STMN1 binds to two moles of tubulin dimers through the stathmin-like domain (SLD).When STMN1 sequesters tubulin into the T2S complex, tubulin becomes non-polymerizable. Without tubulin polymerization, there is no microtubule assembly.STMN1 also promotes microtubule disassembly by acting directly on the microtubule ends.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Human Stathmin 1, His Tag (ST1-H5149) is expressed from E. coli cells. It contains AA Ala 2 - Asp 149 (Accession # NP_981946).
