Western blot analysis of purified brain tubulin untreated (lanes 1,3,5) or treated with ERK2 kinase to phosphorylate Ser-172 (lanes 2,4,6). The blot was probed with anti-β-Tubulin (a.a. 168-177) (lanes 1 & 2), anti-β-Tubulin (Ser-172) (lanes 3 & 4), and anti-β-Tubulin (TM1541) (lanes 5 & 6).

β-Tubulin (central region)
Microtubules (MTs) are cytoskeletal elements that play an essential role in cell division and cytoplasmic organization. MTs are dynamic polymers of α/β-tubulin heterodimers. At least two populations of MTs, called dynamic and stable according to their rates of turnover, are readily distinguishable in cells. The proteins associated with MTs (MAPs) are among the best-known factors that regulate MT dynamics and stability. In addition, a variety of different post-translational modifications may also regulate MT dynamics and stability. Phosphorylation is one of these modifications and it can occur on serine, threonine, and tyrosine residues in β-Tubulin isoforms. Multiple kinases can phosphorylate Ser-444 at the C-terminus of βIII-Tubulin in vitro. Unphosphorylated Ser-444 in βIII-Tubulin is an early marker for cells of neuronal lineage, while phosphorylation of Ser-444 is upregulated after neuronal maturation and may preferentially occur in assembled MTs. By contrast, Cdk1 phosphorylation of Ser-172 in β-Tubulin occurs in mitotic cells and may impair tubulin incorporation into microtubules.
Antigen Affinity Purified
βIII-Tubulin synthetic peptide (coupled to KLH) corresponding to amino acid residues from the central region of human βIII-Tubulin. This sequence is identical to similar regions in βI, βII, and βIII-Tubulin isotypes, and is well conserved in tubulins from most eukaryotic species.
