Catenin, Delta 1 (CTNND1) Antibody – Mouse Monoclonal

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. Read-through transcription also exists between this gene and the neighboring upstream thioredoxin-related transmembrane protein 2 (TMX2) gene. [provided by RefSeq]

CTNND1: an Arm repeat protein that interacts with varied components such as cadherin, small G proteins, kinases, and the Kaiso transcriptional repressor. A downstream modulator of Wnt/beta-catenin signaling pathway whose stability may be regulated downstream of Dsh. Required for the invasiveness of E-cadherin-deficient cells. A signal coordinator between cadherins and Rho-family GTPases to regulate cytoskeletal changes required during dendritic spine and synapse development. The association of catenins with cadherins produces a complex which is linked to the actin filament network, and which seems to be of primary importance for cadherins cell-adhesion properties. Thirty two splice-variant isoforms have been described.
