General description

Tubulin alpha-1 chain (UniProt P09733; also known as alpha-tubulin) is encoded by the TUB1 gene (Gene ID 854889) in yeast. Microtubules are dynamic protein filaments involved in a wide variety of cellular activities ranging from mitosis and transport events to cell movement and the maintenance of cell shape. Microtubules are assembled from α- and β-tubulin subunits, both of which are subjected to posttranslational modifications, including the removal of the C-terminus aromatic amino acid from α-tubulin (tyrosine in mammals and phenylalanine in yeast) by carboxypeptidase actifvity. Because the C-terminus tyrosine/phenylalanine is preceded by glutamate (E) residues, the detyrosinated/dephenylalaninated α-tubulin is also referred to as Glu-tubulin. While tyrosine can be reattached to the C-terminus of the Glu-tubulin by tubulin-tyrosine ligase in mammals, phenylalanine is not added posttranslationally to the Glu-tubulin in yeast despite the presence of the yeast YBR094w gene that exhibits significant homology to tubulin-tyrosine ligase in other organisms.

Specificity

Expected to react with a broad range of species based on 100% sequence homology.
Reacts with alpha-tubulin with phenylalanine (yeast) or tyrosine (mammalian and chicken) at the C-terminus (PMID 6204858). Does not react toward posttranslationally modified alpha-tubulin lacking the C-terminus Phe or Tyr.

This Anti-alpha-Tubulin Antibody, tyrosinated, clone YL1/2 is validated for use in Western Blotting, Immunocytochemistry, Immunohistochemistry, Electron Microscopy, ELISA and Radioimmunoassay for the detection of alpha-Tubulin.
Western Blotting Analysis: 1.0 µg/mL from a representative lot detected tyrosinated alpha-tubulin in 10 µg of C2C12 cell lysate.
Immunocytochemistry Analysis: 4.0 µg/mL from a representative lot detected tyrosinated alpha-tubulin in A431, HeLa and HUVEC cells.
Immunocytochemistry Analysis: Representative lots detected phenylalaninated alpha-tubulin immunoreactivity in yeast and tyrosinated alpha-tubulin immunoreactivity in HEK293 cells (Kilmartin J.V., et al. (1982). J Cell Biol. 93(3):576-582; Bandyopadhyay, B., et al. (2007). J Biol Chem. 282(22):16454-16464).
Immunohistochemistry Analysis: A representative lot detected microtubules tyrosinated alpha-tubulin immunoreactivity in mid-streak level section of Hamburger-Hamilton stage 4 (HH4) chick embryos (Nakaya, Y., et al. (2008). Nat. Cell Biol. 10(7):765-775).
Electron Microscopy Analysis: Representative lots detected microtubules phenylalaninated alpha-tubulin immunoreactivity using crude yeast nuclear envelope preparations and microtubules tyrosinated alpha-tubulin immunoreactivity in NIH/3T3 cells (Wehland, J., and Willingham, M.C. (1983). J Cell Biol. 97(5 Pt 1):1476-1490; Kilmartin J.V., et al. (1982). J Cell Biol. 93(3):576-582).
ELISA Analysis: The antigenicity of clone YL1/2 was determined by competitive ELISA using pig brain-derived tubulin against alpha-tubulin peptides with or without Tyr/Phe at the C-terminal end (Wehland, J., et al. (1984). EMBO J. 3(6):1295-1300).
Radioimmunoassay Analysis: The immunoreactivity of clone YL1/2 toward chick brain tubulin and yeast tubulin was determined by radioimmunoassays (Kilmartin J.V., et al. (1982). J Cell Biol. 93(3):576-582).

Trypanosoma brucei, the causative agent of African sleeping sickness, has a flagellum that is crucial for motility, pathogenicity, and viability. In most eukaryotes, the intraflagellar transport (IFT) machinery drives flagellum biogenesis, and anterograde IFT requires kinesin-2 motor proteins. In this
