TSPAN5 (Tetraspanin 5): TSPAN5 is a gene that encodes a protein from the tetraspanin family, which is involved in cell signaling, adhesion, and migration. Tetraspanins help organize various cellular processes and play important roles in immune system function and cancer metastasis. TSPAN5 may also contribute to neural development and synaptic function, though its precise roles and impact on health and disease are still under investigation.
