CTNNB1 (beta-catenin) binds with high affinity to the distal Cadherin cytoplasmic tail.
Cadherin recruits CTNNA1 (alpha-catenin) to the complex.
CTNNA1 (alpha-catenin) binds to Actin filaments directly
CTNNA1 (alpha-catenin) and can also associate with other actin-binding proteins (MLLT4 or Formin)
CTNND1 (delta-catenin or p120) binds directly to Cadherin independently of the other catenins.
Catenins/Cadherin complex can further interact with a range of singaling molecules which participate in either cellular signaling or control of cytoskeletal dynamics.
Stability of Cadherin/Catenins complex and thereby the integrity of adherens junctions is controlled by phosphorylation/dephosphorylation.
