Opis

Opis ogólny

Actin, cytoplasmic 1 (UniProt P60709; also known as beta-actin, PS1TP5-binding protein 1) is encoded by the ACTB (also known as BRWS1, PS1TP5BP1) gene (Gene ID 60) in human. Post-translational protein arginylation is mediated by Arg–transfer RNA (-tRNA) protein transferase (Ate1; arginyltransferase). β- and γ-actins are the major structural components of the actin cytoskeleton in nonmuscle cells. Despite their similarity, the β-, but not the γ-, actin is N-terminally arginylated in vivo, where the first two N-terminal amino acids are removed and replaced with an arginine (from NH2-MDDDIAAL- to NH2-RDDIAAL-). In the absence of arginylation, actin forms aggregates during cell-free polymerization. Fibroblasts derived from Ate1 knockout (KO) mice show collapsed lamella, which can be rescued by reintroducing N-terminally arginylated β-actin into the Ate1 KO cells. Intracellular actin polymer levels are shown to drastically decrease in arginylation-deficient cells, which results from changes in actin polymerization properties.

Specyficzność

This polyclonal antibody detects beta-actin posttranslationally modified by the removal of Met1 and Asp 2 and the arginylation of Asp3. This antibody does not react with beta-actin with unmodified N-terminus.

Immunogen

C-terminally KLH-conjugated linear peptide corresponding to human beta-actin N-terminal sequence with arginylation modification.

Epitope: N-terminus.

Zastosowanie

Immunocytochemistry Analysis: 2.0 µg/mL from a representative lot detected N-terminally arginylated beta actin in HUVECs and HeLa cells.

Western Blotting Analysis: 2.0 µg/mL from a representative lot detected N-terminally arginylated beta actin in human (HeLa, HEK293, HepG2, HUVEC, Jurkat, PC3), rat (PC-12 pheochromocytoma), and murine (C2C12 myoblast, NIH/3T3, and Raw 264.7) cell lysates, as well as in human placenta and mouse brain tissue homogenates.

Dot Blot Analysis: 0.2 µg/mL from a representative lot detected immunogen peptide, but not the corresponding peptide without the N-terminus arginine (Courtesy of Dr. Anna Kashina, University of Pennsylvania, Philadelphia, PA).

Western Blotting Analysis: 0.2 µg/mL from a representative lot detected greatly reduced beta actin N-terminal arginylation modification in Arg-transfer RNA (Arg-tRNA) protein transferase (Ate1) knockout mouse embryonic fibroblasts (Courtesy of Dr. Anna Kashina, University of Pennsylvania, Philadelphia, PA).

Note: Goat serum is found to interfere with the staining by this polyclonal antibody, BSA is recommended for sample blocking when using this product.
