Application


  • VCP maintains lysosomal homeostasis and TFEB activity in differentiated skeletal muscle.: The article discusses the maintenance of lysosomal function and transcription factor activity in muscle cells, which may be influenced by small molecular agents like Leu-Leu methyl ester hydrobromide that affect cellular processes (Arhzaouy et al., 2019).

Biochem/physiol Actions

Leu-Leu methyl ester (LLME, Leu-Leu-OMe) may be used to induce protease-dependent cell death (apoptosis) in immune cells such as mast cells, phagocytes, monocytes/macrophages and natural killer cells.
Peptide toxic to natural killer T cells.
