Arf-GAP With Coiled-Coil, ANK Repeat And PH Domain Containing Protein 1 (ACAP1) Antibody (Biotin)

Background

ACAP1 is a multifunctional protein that acts as a GTPase-activating protein (GAP) for ADP-ribosylation factors (Arfs), small GTP-binding proteins involved in vesicle trafficking and membrane dynamics. It contains a pleckstrin homology (PH) domain, ankyrin repeats, and a coiled-coil region, enabling interactions with phospholipids and proteins. ACAP1 is involved in clathrin-mediated endocytosis and recycling of membrane proteins like integrins and nutrient receptors, regulating cellular adhesion, migration, and nutrient uptake. It plays a significant role in immune and migrating cells by recycling surface proteins critical for cellular responses. Dysregulation of ACAP1 has been linked to impaired membrane trafficking, contributing to diseases such as cancer and immune disorders.
