Activity summary

SHANK1 also known as SH3 and multiple ankyrin repeat domains protein 1 plays an important role in the structural organization of synapses. It is a scaffold protein found in postsynaptic density where it interacts with other molecules to maintain synaptic architecture. The protein has a molecular mass of approximately 240 kDa. Expression of SHANK1 is most abundant in the brain especially in the hippocampus and cortex where it is essential for establishing and stabilizing synaptic connections during neuronal development.

Biological function summary

SHANK1 participates in the formation of macromolecular complexes that are critical for synaptic signaling and plasticity. It forms complexes with other postsynaptic proteins including PSD-95 and Homer which together coordinate the organization of synaptic receptors and signaling molecules. This interaction determines synaptic strength and plays a role in the modulation of synaptic transmission influencing the communication between neurons.

Pathways

SHANK1 is involved in the glutamatergic synaptic transmission pathway which is important for neural communication and cognitive functions such as learning and memory. Through this pathway SHANK1 interacts with NMDA receptors and mGluR receptors facilitating the propagation of excitatory signals. It also connects with proteins like SAPAP and cortactin which help stabilize the synaptic complex influencing cytoskeletal dynamics and synaptic plasticity.

Associated diseases and disorders

SHANK1 has been implicated in autism spectrum disorders and schizophrenia where disrupted synaptic signaling plays an important role. Mutations in SHANK1 or its regulatory interactions can lead to altered neuronal connectivity and synaptic function which contribute to the pathology of these conditions. The protein's interaction with SHANK3 and other synaptic proteins like neuroligin emphasizes its role in synaptic disorders as these partners also participate in maintaining synaptic structure and function.
