General description

The catenins (α, β, γ) are cytoplasmic proteins found in varying developing and adult tissues. α- N-catenin is a cadherin-binding protein, that plays a crucial role in cadherin-mediated cell-cell adhesion. It is widely expressed in the nervous system. α-Catenin (CAP102, 102 kDa), originally described as an E-cadherin associated protein, has been shown to associate with N-cadherin and P-cadherin. Within its conserved region α-catenin shows 30% identity to vinculin. There are at least two subtypes of α-catenin: α-E-catenin and α-N-catenin (102 kDa). The predominant form is α-E-catenin. Alternative spliced forms of α-N-catenin include α-N-catenin I and α-N-catenin II. The ratio of the two isoforms changes during development: isoforms II is more abundant than isoform I in early embryonic development, whereas isoform I is predominant in the adult stage.


synthetic peptide corresponding to a region located near the N-terminus of human α-N-catenin (amino acids 171-186) conjugated to KLH. This sequence is identical in mouse and chicken α-N-catenin. It is not found in α-E-catenin, β-catenin, and γ-catenin.


α-N-Catenin antibody is suitable for microarray and western blot at a dilution of 1:1,000 by using cytosolic fraction of mouse brain.

Biochem/physiol Actions

Catenins bind directly or indirectly to the conserved cytoplasmic tail domain of the cell adhesion cadherins. The association of catenins to cadherins produces a complex, which is linked to the actin filament network. Catenins/cadherin complexes play an important role in mediating cell adhesion, transduction of cell-cell contact positional signals to the cell interior, and may play a crucial role in cell differentiation. The expression of α-N-catenin is more restricted and this form predominates in the brain and is localized at synaptic junctions.
