General description

Anti-α-Tubulin antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the hybridoma AA13 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with rat brain tubulin.
Tubulin α 1a (TUBA1A) is a member of α-tubulin gene family. It is encoded by the gene mapped to human chromosome 12q13.12. Tubulin α 1a is a vital structural subunit of microtubules that are temporarily expressed in almost all post-mitotic neurons during neuronal development.
The encoded protein structure contains core of two β-sheets enclosed by α-helices. TUBA1A is characterized with an amino-terminal domain with the guanine nucleotide-binding region, an intermediate domain associated with interprotofilament lateral contacts and the modulation of tubulin curvature, and a carboxy-terminal domain that contains region involved in interacting with microtubule-associated proteins (MAPs) and molecular motors, such as kinesins and dynein.

Immunogen

rat brain tubulin.

Application

Anti-α-Tubulin antibody, Mouse monoclonal has been used in western blotting.
The antibody has been used in various immunochemical techniques including immunoprecipitation, immunocytochemistry, and immunohistochemistry.

Biochem/physiol Actions

Gene mutation of tubulin α-1A (TUBA1A) is observed in perisylvian asymmetrical polymicrogyria, polymicrogyria-like cortical dysplasia, and microlissencephaly in foetal cases. Alteration in the expression of the gene impairs neural migration and causes lissencephaly (LIS).
Tubulin is the major building block of microtubules, which is a structural and mobile element in mitosis, intracellular transport, flagellar movement and the cytoskeleton. Monoclonal antibodies recognizing α-tubulin, together with monoclonal antibodies to other tubulin types (α-tubulin isotypes I, II, and III, tyrosine tubulin and acetylated- α -tubulin) provide a specific and useful tool in studying the intracellular distribution of tubulin, and the static and dynamic aspects of the cytoskeleton. In addition, the various tubulin forms have been implicated in cancerous processes and are thus suggested as potential targets for cancer therapy.

Target description

Tubulin is a cylindrical, filamentous structure is present inalmost all eukaryotic cells.

Many microRNAs (miRNAs) exist alongside abundant miRNA isoforms (isomiRs), most of which arise from post-maturation sequence modifications such as 3' uridylation. However, the ways in which these sequence modifications affect miRNA function remain poorly understood. Here, using human miR-27a in cell

The ubiquitin E3 ligase anaphase-promoting complex/cyclosome (APC/C) drives degradation of cell cycle regulators in cycling cells by associating with the coactivators Cdc20 and Cdh1. Although a plethora of APC/C substrates have been identified, only a few transcriptional regulators are described
