AMAP-1 Activators

AMAP-1, also known as ASAP1 (ArfGAP with SH3 domain, ankyrin repeat, and PH domain 1), is a multifunctional protein that plays a pivotal role in cellular dynamics and architecture. As a GTPase-activating protein (GAP) for the small GTPase Arf1, AMAP-1 regulates the Arf1-mediated remodeling of the actin cytoskeleton, which is crucial for various cellular processes including cell migration, adhesion, and vesicular trafficking.

AMAP-1 is characterized by the presence of several protein interaction domains, including the SH3 domain, the PH domain, and ankyrin repeats. These domains enable AMAP-1 to interact with a wide range of other proteins, thereby integrating signals that coordinate actin dynamics and membrane trafficking. The PH domain, in particular, binds to phospholipids in the cell membrane, which can recruit AMAP-1 to specific cellular locations, especially those undergoing active remodeling.The protein is known to be involved in cancer cell invasiveness, and its expression is upregulated in certain types of cancers, where it has been associated with the progression of the disease. The exact mechanisms by which AMAP-1 contributes to disease progression are still under investigation, but it is believed to involve the modulation of cellular signaling pathways that control cell shape and motility.
