α6-Tubulin Phospho-Regulation

Antibody Sampler Kit

$395

Microtubules (MTs) are cytoskeletal elements that play an essential role in cell division and cytoplasmic organization. MTs are dynamic polymers of a/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 α- and β-Tubulin isoforms. Multiple kinases can phosphorylate Ser-444 at the C-terminus of βIII-Tubulin in vitro, and unphosphorylated Ser-444 may be an early marker for cells of neuronal lineage. Cdk1 can phosphorylate Ser-172 in β-Tubulin during mitosis and this may impair tubulin incorporation into microtubules. In α-tubulin, PKC can phosphorylate Ser-165 leading to increased cell motility in human breast cells.

Western blot analysis of 250 ng/lane of a1-Tubulin unphosphorylated (lanes 1, 3, & 5) or phosphorylated at Ser-165 with PKCα (lanes 2, 4, & 6). The blots were probed with anti-α6-Tubulin (a.a. 160-169) (TP4281; lanes 1 & 2), anti-α6-Tubulin (Ser-165) (TP4131; lanes 3 & 4), and anti-α-Tubulin (C-terminus) (TM4111; lanes 5 & 6).

Western blot analysis of α-tubulin expression in human A431 (lane 1), HUVEC (lane 2), Jurkat (lane 3), mouse J774.1 (lane 4), human PC-3 (lane 5), rat PC12 (lane 6), and mouse C2C12 (lane 7). The blot was probed with anti-α-Tubulin (C-terminus) at 1:1000.

KIT SUMMARY

The α-tubulin phospho-regulation kit can be used to examine phosphorylation of α-tubulin (Ser-165) relative to the total expression of α-tubulin. The kit includes rabbit polyclonal and mouse monoclonal antibodies to detect total α-tubulin, and secondary reagents for rabbit polyclonal and mouse monoclonal antibody detection.
