T-cadherin also known as cadherin 13, H-cadherin (heart) (CDH13) is a unique member of cadherin superfamily because it lacks the transmembrane and cytoplasmic domains and is anchored to the cells membrane through the GPI anchor. Classical cadherins are necessary for cell–cell contacts, dynamic regulation of morphogenetic processes in embryos and tissue integrity in adult organism. Cadherins function as membrane receptors mediating outside-in signals, activating small GTPases and beta-catenin/Wnt pathway, and resulting in dynamic cytoskeleton reorganization and changes in the phenotype.
