TBC1D22A Attivatori

TBC1D22A is a protein encoded by the TBC1D22A gene in humans. Its name reflects its classification: TBC1 indicates that it contains a TBC (Tre-2, Bub2, and Cdc16) domain, which is typically associated with proteins that have GTPase-activating protein (GAP) activity towards small GTPases of the Rab family. The 'D22A' suffix denotes its specific gene identifier within this family.Proteins in this group, including TBC1D22A, are regulators of intracellular vesicle trafficking. They function by inactivating Rab GTPases, which play critical roles in directing vesicle transport along cytoskeletal tracks to different cellular compartments such as the Golgi apparatus, endosomes, lysosomes, and the plasma membrane. By acting as GAPs, TBC domain-containing proteins like TBC1D22A help control the timing of vesicle fusion and release, ensuring that cargo is delivered to the correct location within the cell.

The TBC1D22A protein may have specific substrates among the Rab GTPases, although the precise Rab targets and the pathways that TBC1D22A regulates are not well-characterized compared to other members of the TBC domain-containing protein family. It is likely involved in processes such as membrane trafficking, signal transduction, and cellular growth and differentiation.Mutations or dysregulation of proteins that control vesicle trafficking, like TBC1D22A, can lead to a wide array of cellular dysfunctions and are often implicated in diseases including neurological disorders, cancer, and metabolic syndromes.
