CTNNA1/CTNNA2

disease:Abnormalities of alpha-catenin are involved in the process of cancer invasion and metastasis.,function:Associates with the cytoplasmic domain of a variety of cadherins. The association of catenins to cadherins produces a complex which is linked to the actin filament network, and which seems to be of primary importance for cadherins cell-adhesion properties. May play a crucial role in cell differentiation.,PTM:Sumoylated.,similarity:Belongs to the vinculin/alpha-catenin family.,subcellular location:Found at cell-cell boundaries and probably at cell-matrix boundaries.,subunit:Binds MLLT4 and F-actin (By similarity). Interacts directly with PSEN1 and CTNNB1 to form part of the PSEN1/cadherin/catenin adhesion complex. Interacts with ARHGAP21 and with JUB.,tissue specificity:Expressed ubiquitously in normal tissues.,
