**Recombinant human CENTD3 protein** (also known as ARAP3) is a key regulatory protein involved in cellular signaling and cytoskeletal dynamics. It belongs to the centaurin delta family, characterized by multiple functional domains, including an ArfGAP (ADP-ribosylation factor GTPase-activating protein) domain, a RhoGAP (Rho GTPase-activating protein) domain, pleckstrin homology (PH) domains, and ankyrin (ANK) repeats. These domains enable CENTD3 to interact with phosphoinositides and small GTPases, such as Arf and Rho family proteins, facilitating its role in coordinating membrane trafficking, cell migration, and actin cytoskeleton reorganization.
CENTD3 is notably linked to phosphoinositide 3-kinase (PI3K) signaling pathways, acting as a downstream effector that translates lipid signals into cytoskeletal changes. It regulates cell polarization and directional movement in response to extracellular cues, making it critical in processes like immune cell chemotaxis and cancer metastasis. Dysregulation of CENTD3 has been implicated in pathological conditions, including tumor invasiveness and impaired immune responses.
Recombinant CENTD3 protein, produced via heterologous expression systems like *E. coli* or mammalian cells, is widely used in biochemical studies to dissect its GAP activity, lipid-binding specificity, and interactions with signaling partners. It also serves as a tool for drug discovery targeting PI3K-related diseases. Structural and functional insights from recombinant CENTD3 have advanced understanding of how dual GTPase regulation fine-tunes complex cellular behaviors.
