ADAP1 (ArfGAP with dual PH domains 1), also known as CENTD1. is a multidomain protein involved in regulating cellular signaling and membrane trafficking processes. It belongs to the ArfGAP family, which modulates the activity of ADP-ribosylation factors (Arfs), small GTPases critical for vesicle formation, cytoskeletal reorganization, and receptor trafficking. ADAP1 uniquely combines an N-terminal ArfGAP domain with two pleckstrin homology (PH) domains, enabling dual functionality in GTPase regulation and phosphoinositide binding. The PH domains allow ADAP1 to interact with membrane phospholipids, such as phosphatidylinositol (3.4.5)-trisphosphate [PI(3.4.5)P3], facilitating its localization to specific subcellular compartments.
ADAP1 plays a role in neuronal development, synaptic plasticity, and cancer progression. Studies suggest its involvement in PI3K/AKT signaling pathways, where it may act as a scaffold or modulator. In neurons, ADAP1 interacts with the cytoplasmic tail of the metabotropic glutamate receptor (mGluR), influencing receptor trafficking and downstream signaling. Dysregulation of ADAP1 has been linked to neurodevelopmental disorders and tumorigenesis, highlighting its potential as a therapeutic target.
Recombinant ADAP1 protein is engineered for in vitro studies to dissect its molecular interactions, enzymatic activity (e.g., ArfGAP assays), and structural properties. Produced via bacterial or mammalian expression systems, it retains functional domains for binding assays, kinase/phosphatase studies, and inhibitor screening. Its applications extend to exploring ADAP1’s role in membrane dynamics, cell migration, and disease mechanisms. Research using recombinant ADAP1 has advanced understanding of its cross-talk with Arf GTPases, phosphoinositides, and signaling adaptors, offering insights into targeted drug design for cancers or neurological conditions.
