Crystal structure of the TIG domain of human calmodulin-binding transcription activator 1 (CAMTA1)

Disease

[CMTA1_HUMAN] Defects in CAMTA1 are the cause of cerebellar ataxia, non-progressive, with mental retardation (CANPMR) [MIM:614756]. A neurodevelopmental disorder characterized by mildly delayed psychomotor development, early onset of cerebellar ataxia, and intellectual disability later in childhood and adult life. Other features may include neonatal hypotonia, dysarthria, and dysmetria. Brain imaging in some patients shows cerebellar atrophy. Dysmorphic facial features are variable.^[1]

Function

[CMTA1_HUMAN] Transcriptional activator. May act as a tumor suppressor.^[2][3]

About this Structure
