ARAP2 (ArfGAP With RhoGAP Domain, Ankyrin Repeat, and PH Domain 2): ARAP2 is a protein that plays a key role in cell signaling by acting as a GTPase-activating protein for Arf and Rho family members. It is important for regulating cell migration and cytoskeletal organization, with potential implications in cancer metastasis and cellular morphology.
