Gene: Ctnna2 (catenin alpha 2) Rattus norvegicus
Symbol: Ctnna2
Name: catenin alpha 2
Description: Predicted to have actin filament binding activity and identical protein binding activity. Predicted to be involved in several processes, including modification of postsynaptic actin cytoskeleton; negative regulation of Arp2/3 complex-mediated actin nucleation; and nervous system development. Predicted to localize to several cellular components, including the extrinsic component of synaptic membrane; hippocampal mossy fiber to CA3 synapse; and parallel fiber to Purkinje cell synapse. Human ortholog(s) of this gene implicated in complex cortical dysplasia with other brain malformations. Orthologous to human CTNNA2 (catenin alpha 2); PARTICIPATES IN arrhythmogenic right ventricular cardiomyopathy pathway; endometrial cancer pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; bisphenol A; dibutyl phthalate.
Type: protein-coding
Also known as: catenin (cadherin associated protein), alpha 2; catenin alpha-2; catenin, alpha 2; Catna2; LOC297357
