Cadherins are a family of Ca2+-dependent intercellular adhesion molecules that play a central role in controlling morphogenetic movements
during development. Their function is regulated by association with the actin cytoskeleton by a complex of cytoplasmic proteins called the
catenins (α, β, γ). Members of the cadherin family include P-cadherin, E-cadherin (uvomorulin), N-cadherin (neural cadherin), R-cadherin,
cadherin 5, L-CAM, and EP-cadherin. N-cadherin mRNA is found at elevated levels in brain and heart and at a much lower level in liver.
Mechanisms such as mRNA expression, cytokine modulation, and protease-mediated turnover modulate N-cadherin protein levels during
development. In addition, N-cadherin function is indirectly regulated by endogenous kinases and phosphatases. Tyrosine phosphorylation of
β-catenin complexed with N-cadherin results in dissociation of N-cadherin from actin. However, N-cadherin also interacts with a PTP1B-like
phosphatase that dephosphorylates β-catenin and promotes N-cadherin/actin association. Thus, N-cadherin is an integral adhesion molecule
whose function is regulated by protein-protein interactions and phosphorylation/dephosphorylation events.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
