CTNNA1 antibody (pSer641)

Catalog No. ABIN401554

Product Details anti-CTNNA1 Antibody

Target: CTNNA1 (Catenin (Cadherin-Associated Protein), alpha 1, 102kDa (CTNNA1))

Binding Specificity: pSer641

Reactivity: Human, Mouse

Host: Rabbit

Clonality: Polyclonal

Conjugate: This CTNNA1 antibody is un-conjugated

Application: Western Blotting (WB)

Specificity: This antibody detects endogenous levels of Alpha-Catenin only when phosphorylated at Serine 641.

Purification: Immunoaffinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

Immunogen: Peptide sequence around the phosphorylation site of Serine 641 (D-D-Sp-D-F) derived from Human Alpha-Catenin.

Target Details for CTNNA1

Target: CTNNA1 (Catenin (Cadherin-Associated Protein), alpha 1, 102kDa (CTNNA1))

Alternative Name: Catenin alpha-1 / CTNNA1 (CTNNA1 Products)

Background: The distinct peripheral cytosolic proteins, alpha, beta and gamma-catenin (102, 94 and 86 kDa) found in many tissues bind to the conserved cytoplasmic tail domain of the cell-adhesion cadherins. Catenins link E-cadherin to other integral membrane or cytoplasmic proteins and are modulated by Wnt-1 proto-oncogene. They are good candidates for mediating transduction of cell-cell contact positional signals to the cell interior. Absence of alpha-catenin is found in certain tumor cell lines and reduced levels in certain human carcinomas. Beta-catenin binds directly to the cytoplasmic tail of E-cadherin. It binds to the N-terminus of alpha-catenin and interacts with the protein product of the tumor suppressor gene APC. This interaction involves a 15-aa repeat in the APC. Beta-catenin cell levels seem to be controlled by APC. The central core region of beta-catenin is involved in mediation of cadherin-catenin complex interaction with EGFR.Synonyms: Alpha Catenin, Alpha E-catenin, Cadherin-associated protein, NY-REN-13 antigen
