Supplementary information

Semaphorin 3A also known as SEMA3A is a secreted protein that plays a role as a guidance cue in the nervous system by binding to receptors like neuropilin-1 and plexin-A. It weighs approximately 95 kDa. Expressed mainly in neurons SEMA3A influences neuronal wiring during development. In addition to neural tissues its expression occurs in endothelial cells and immune cells suggesting a role in vascular and immune system functioning.
Biological function summary

Semaphorin 3A influences cell migration axonal guidance and organogenesis. It functions as a repulsive guidance molecule that unfavorably influences the direction of growing axons and migrating neurons. SEMA3A does not act alone but is part of a complex involving neuropilin and plexin for effective signal transduction. These signaling complexes ensure that axonal pathways form correctly and aid in correct neural network formation.

Pathways

Semaphorin 3An importantly integrates into the axon guidance and immune response pathways. In the axon guidance pathway it repulses axons and influences the cytoskeletal dynamics by interacting with proteins such as collapsin response mediator protein (CRMP) and Rac1. SEMA3A participates in immune response through its influence on immune cell migration and positioning ensuring an appropriate immune response.

Anomalies in Semaphorin 3A activity relate to cancer and neuropathic pain. Aberrant SEMA3A expression and signaling can contribute to tumor progression and metastasis often working with neuropilin-1 and vascular endothelial growth factor (VEGF) in cancerous processes. Furthermore changes in SEMA3A signaling pathways have links to neuropathic pain where it collaborates with CRMP-2 to alter pain perception and neuropathic pain pathways.
