General description
Catenin delta-2 (UniProt: Q9UQB3; also known as Delta-catenin, GT24, Neural plakophilin-related ARM-repeat protein, NPRAP, Neurojungin) is encoded by the CTNND2 (also known as NPRAP) gene (Gene ID: 1501) in human. Delta Catenin is a component of the cadherin-catenin cell adhesion complex and is enriched in synaptosomes. Catenin Delta 2 is a member of the beta-catenin superfamily and is expressed in the brain where it is required for normal cognitive development and its highest expression is observed in fetal brain. Catenin Delta 2 is phosphorylated by Cdk5 and by GSK-3beta. Catenin Delta 2 plays a critical role in neuronal development, particularly in the formation and/or maintenance of dendritic spines and synapses. It is also involved in the regulation of Wnt signaling where it acts on beta-catenin turnover, facilitating beta-catenin interaction with GSK3beta, phosphorylation, ubiquitination, and degradation. When bound to ZBTB33 (Zinc Finger and BTB Domain Containing 33), it functions as a transcriptional activator. Catenin delta-2 also promotes the disruption of E-cadherin based adherens junction to favor cell spreading upon stimulation by hepatocyte growth factor. Two isoforms of Catenin delta-2 have been reported that are produced by alternative splicing. It has nine Armadillo (ARM) repeats and a coiled coil region (aa 49-84). Defects in CTNND2 gene are known to cause autism and delayed acquisition of psychomotor skills. (Ref.: Yuan, L et al. (2015). J. Biol. Chem. 290(17):10947-57).
