AcrAP1 (AP1-Z1) is an antimicrobial peptide found in the venom of the Arabian scorpion (Androctonus crassicauda). It exhibits antibacterial properties, effectively inhibiting the growth of both Gram-positive and Gram-negative bacteria, as well as yeasts. AcrAP1 also displays antitumor activity by promoting apoptosis in cancer cells and inhibiting angiogenesis, making it a potential candidate for cancer treatment research.
