Angelman syndrome (AS) is a neurodevelopmental disorder characterized by developmental delays, intellectual disabilities, impaired language and speech, and movement defects. Most AS cases are caused by dysfunction of a maternally-expressed E3 ubiquitin ligase (UBE3A, also known as E6 associated protein, E6-AP) in neurons. Currently, the mechanism on how loss-of-function of the enzyme influences the nervous system development remains unknown. We hypothesize that impaired metabolism of proteins, most likely those related to E6-AP substrates, may alter the developmental trajectory of neuronal structures including dendrites, spines and synaptic proteins, which leads to disrupted activity/experience-dependent synaptic plasticity and maturation. To test this hypothesis, …
