Description

Involved in several processes, including chordate embryonic development; positive regulation of brain-derived neurotrophic factor receptor signaling pathway; and regulation of cell-cell adhesion mediated by cadherin. Predicted to localize to cytoplasm and nucleus. Used to study Huntington's disease. Human ortholog(s) of this gene implicated in Huntington's disease and Parkinson's disease. Is expressed in brain; head; intermediate cell mass of mesoderm; and post-vent region. Orthologous to human HTT (huntingtin).
