Recombinant human DDEF1 protein, also known as ASAP1 (ArfGAP with SH3 Domain, Ankyrin Repeat, and PH Domain 1), is a synthetically produced version of the naturally occurring DDEF1 protein encoded by the *ASAP1* gene. DDEF1 is a multidomain scaffolding protein involved in regulating diverse cellular processes, including cell migration, membrane trafficking, and signal transduction. It contains an N-terminal ArfGAP domain that hydrolyzes GTP-bound ADP-ribosylation factors (Arfs), a PH domain for membrane association, and C-terminal SH3 and ANK repeats mediating protein-protein interactions. Dysregulation of DDEF1 expression is linked to cancer progression, as it promotes tumor cell invasion, metastasis, and angiogenesis by modulating cytoskeletal dynamics and integrin signaling pathways. Recombinant DDEF1 is typically expressed in *E. coli* or mammalian systems, purified via affinity tags (e.g., His-tag), and used to study its biochemical properties, structure-function relationships, and role in cellular mechanisms. It serves as a critical tool in drug discovery targeting DDEF1-associated pathways in oncology.
