Target Details for CTNNA1

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

Alternative Name: alpha-Catenin

Background: The catenins (alpha-, beta-, and gamma-) are cytoplasmic proteins that bind to the highly conserved cytoplasmic tail of E-Cadherin. The cadherins, transmembrane adhesion molecules, are found with catenins at adherens junctions (zonula adherens). These junctions are critical for cell-cell adhesion, signal transmission between neighboring cells, and for the anchoring of the actin cytoskeleton. alpha-Catenin (CAP102) shows homology to vinculin, while beta-Catenin is similar to plakoglobin or the Drosophila armadillo gene product. alpha-Catenin was identified as an E-Cadherin-associated protein, however, it also appears to interact with other cadherin family members. There are at least two subtypes of alpha-Catenin: alphaE-Catenin and alphaN-Catenin. The predominant form is known as alphaE-Catenin. It is ubiquitously expressed, but at low levels in the nervous system. The expression of alphaN-Catenin is more restricted and this form predominates in the brain. Increased tyrosine phosphorylation of adherens junction proteins can disrupt catenin-cadherin complexes, leading to changes in cell adhesion properties. It has been noted that down-regulation of this group of proteins often precedes metastasis. In fact, data suggests a correlation between deletions within the alpha-Catenin gene and the development of prostate cancer. This antibody is routinely tested by western blot analysis.
