Anti-alpha-Tubulin Antibody, tyrosinated, clone YL1/2

产品说明

一般描述

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.

特异性

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.
