P120ctn is a more newly found catenin , studies revealed that it is also an important molecule in e - cadherin mediated cell - cell adhesion , and phosphorylated tyrosine in p120ctn were evidenced . translocation of p120ctn occurred in cancer cells and tissues . evidences showed that there were a key relationship between p120ctn translocation and tumoregenesis P120 ~ ( ctn )是发现得较晚的一种连环蛋白，研究发现它也参与上皮钙粘蛋白介导的细胞粘附过程并且不可缺少，同时p120 ~ ( ctn )也和-连环蛋白一样易于酪氨酸残基磷酸化，磷酸化后的p120 ~ ( ctn )也发生转位，并与肿瘤的发生发展有密切关系。
