Function

This gene encodes a member of the Armadillo protein family, which function in adhesion between cells and signal transduction. Multiple translation initiation codons and alternative splicing result in many different isoforms being translated. Not all of the full-length natures of the described transcript variants have been determined.


Clinical significance

Either loss or cytoplasmic localization of p120 is a common feature in the progression of several types of carcinoma.
