This clone recognizes the alpha subunit of tubulin, specifically binding tyrosylated Tubulin (Tyr-Tubulin). The epitope recognized by this antibody appears to be a linear sequence requiring an aromatic residue at the C terminus, with the two adjacent amino acids being negatively charged (represented by Glu-Glu-Tyr in Tyr-Tubulin).
MA1-80017 is predicted to react with amphibia, birds, and echinoderm based on sequence homology. Does not react with nephrotoma suturalis.
This antibody is suitable for use as a loading control.The antibody has been used in epitope tagging procedures to detect proteins tagged with a C-terminal Gly-Gly-Phe epitope. These sequence requirements have been reported to result in some cross-reactivity with other proteins in certain circumstances, including E. coli rec A and oxidized actin.
Alpha Tubulin is a part of a heterodimer consisting of alpha and beta tubulin subunits. The alpha and beta tubulins, which are each about 55 kDa MW, are homologous but not identical. Alpha-beta tubulin heterodimer is the basic building block of microtubules, and this intracellular cylindrical filamentous structure is present in almost eukaryotic cells. Microtubules serve as structural supports and lines of transport within the cell, as well as serving a key role in mitosis. Microtubules of the eukaryotic cytoskeleton perform essential and diverse functions and are composed of a heterodimer of alpha and beta tubulins. The alpha and beta tubulins represent the major components of microtubules, while gamma tubulin plays a critical role in the nucleation of microtubule assembly. There are multiple alpha and beta tubulin genes, which are highly conserved among species. The gene that encodes alpha tubulin is highly similar to the mouse and rat Tuba1 gene. Northern blotting studies have shown that the gene expression is predominantly found in morphologically differentiated neurologic cells.
