Product Information

• Name: Leptomycin A
• Brand: Biosynth
• Description: Leptomycin A is a Streptomyces-produced inhibitor, which is derived from the bacterium Streptomyces spiroverticillatus. It functions by specifically binding to and inhibiting the CRM1 (exportin 1), a nuclear export receptor. This action blocks the nuclear export of proteins that contain a leucine-rich nuclear export signal (NES), thereby leading to their accumulation within the nucleus. The inhibition of CRM1 disrupts various cellular processes, including cell cycle regulation and signal transduction pathways.
