Preparation and Storage

Background: Cadherin-13

Cadherin-13, also known as T-cadherin and H-cadherin, is a 105 kDa member of the cadherin family of transmembrane glycoproteins that mediate calcium-dependent intercellular adhesion (1). However, Cadherin-13 is an atypical member, lacking transmembrane and cytosolic domains and containing a GPI moiety that anchors Cadherin-13 to the plasma membrane (1-2). Human Cadherin-13 is synthesized as a 713 amino acid (aa) precursor that contains a 22 aa signal sequence, a 116 aa propeptide, a 555 aa mature chain, and a second propeptide of 20 aa that is removed in the mature form to reveal the GPI anchor. The mature form contains five cadherin domains and eight potential sites for N-linked glycosylation. Mature human Cadherin-13 shares 96% aa identity with mature mouse Cadherin-13. Cadherin-13 is expressed in various tissues. It is highly expressed in the heart, and in the CNS, Cadherin-13 is expressed in the cerebral cortex, medulla, hippocampus, amygdala, thalamus, and substantia nigra (2). There are higher levels of Cadherin-13 in the adult brain than in developing brain (2). Cadherin-13 is also expressed in skin in the basal layer of the epidermis, lung, liver, kidney, and blood vessels (2). The structural characteristics of Cadherin-13 predict that it is unlikely to function as a true adhesion molecule in vivo (2). It is suggested that it may act rather as a signaling receptor participating in recognition of the environment and regulation of cell motility, proliferation, and phenotype (2). Cellular expression levels of Cadherin-13 in various tissues often correlate, negatively or positively, with the proliferative potential of the cells (2). Cadherin-13 may also act as a suppressor of tumor cell growth (2). This potential role for Cadherin-13 was emphasized by localization of Cadherin-13 gene to chromosome 16q24, a region exhibiting loss of heterozygosity in many solid tumors (2). Allelic loss of chromosome bands 16q24.1-q24.2 and reduced expression of Cadherin-13, as well as hypermethylation of the remaining allele have been detected in a considerable number of human cancers (2).
