说明
-
Recognizes most forms of polyglutamylated tubulin (alpha- and beta-tubulin), independent of the length of the glutamate side chains. No specificity to particular tubulin isoforms nor to tubulin from particular species are observed. Detects also other (poly)glutamylated proteins. Since no consensus modification site is known for protein (poly)glutamylation, the detection is not sequence-specific. However, an acidic environment of the modification site is required. The use of the antibody at too high concentrations obscures its specificity in immunofluorescence.

背景
- Polyglutamylation is a post-translational modification in which glutamate side chains of variable lengths are formed on the modified protein. It is evolutionarily conserved and the most prominent substrate is tubulin, the microtubule (MT) building block. Polyglutamylation has been proposed to be involved in the functional adaptation of MTs, as it occurs within the carboxy-terminal tubulin tails that participate directly in the binding of many structural and motor MT-associated proteins. The recent identification of new substrates of polyglutamylation indicates that this post-translational modification could be a potential regulator of diverse cellular processes and be involved in cell cycle and cell proliferation.
