Relevance to Autism

Conditional stb knockout mice were found to display core autism-like traits, including deficits in social recognition and communication, increased stereotypic behavior, and impaired spatial learning and memory; furthermore, functional analysis of a de novo missense variant in the SYBU gene observed in an ASD proband demonstrated that this variant resulted in the loss of adapter capacity for binding kinesin-1 motors and failure to rescue reduced synapse formation and impaired synaptic transmission and plasticity in neurons from stb cKO mice.

Molecular Function

Syntabulin/GOLSYN is part of a kinesin motor-adaptor complex that is critical for the anterograde axonal transport of active zone components and contributes to activity-dependent presynaptic assembly during neuronal development.
