Semaphorin-3G (SEMA3G): A Multifunctional Signaling Molecule

Molecular Structure and Classification

Semaphorin-3G (SEMA3G) belongs to the class 3 semaphorin family, a group of secreted proteins crucial for cellular signalling and guidance. The protein possesses a characteristic sema domain, a PSI domain (plexin-semaphorin-integrin), and an immunoglobulin-like domain. SEMA3G’s molecular structure enables it to interact with various receptor complexes, primarily neuropilin-2 (NRP2) and plexin family members. This structural arrangement facilitates its diverse biological functions and signalling capabilities across multiple tissue types.

Physiological Functions and Signalling

SEMA3G demonstrates remarkable versatility in its biological roles, participating in various developmental and homeostatic processes:

Neuronal Development: Axon guidance and pathfinding. Neuronal migration regulation, Synaptic plasticity modulation

Vascular System: Angiogenesis regulation, Endothelial cell behaviour control, Vascular patterning

Immune System: Immune cell migration, Inflammatory response modulation, Immune surveillance

The signalling mechanisms of SEMA3G involve complex molecular cascades that often result in cytoskeletal rearrangements and changes in cell behaviour.
