membrane-permeable

Membrane-Permeable Sequence (MPS) is a cell-penetrating peptide (CPP) utilized in the investigation of membrane crossing mechanisms [1].

Tat-NR2BAA is an inactive control peptide of Tat-NR2B9c. It shares a similar sequence with Tat-NR2B9c, but possesses a double-point mutation in the COOH terminal tSXV motif. This mutation renders Tat-NR2BAA unable to bind PSD-95. Tat-NR2B9c, on the other hand, is a membrane-permeable peptide that interferes with PSD-95 NMDAR binding. This interference leads to the decoupling of NR2B- and or NR2A-type NMDARs from PSD-95[1][2].

Dimethyl L-glutamate (Dimethyl glutamate), a membrane-permeable derivative of glutamate, stimulates glucose-induced insulin release, suppresses K_ATP channel activities, inhibits E. gracilis growth, and causes abnormal cell division. This compound is utilized in diabetes research, focusing on glucose transport, phosphorylation, and metabolism.

HIV-1 TAT (48-60) Acetate, a commonly used membrane-permeable carrier peptide, is an arginine-rich basic peptide derived from the human immunodeficiency virus (HIV-1 Tat) protein that enables intracellular delivery of compounds.

TAT-GluN2BCTM is a membrane-permeable peptide that selectively targets active DAPK1 (Death-associated protein kinase 1) for lysosomal degradation, protecting neurons against oxidative stress and NMDAR-mediated excitotoxicity, making it valuable for neuroprotection research studies [1].

TAT-NSF700 Fusion Peptide acetate is a membrane-permeable inhibitor of N-ethyl-maleimide-sensitive factor (NSF), a fusion peptide with potential anti-inflammatory activity.TAT-NSF700 Fusion Peptide acetate interacts with intracellular organelles and can be used to investigate Myocardial ischemia and reperfusion injury.

MPS-Gαi2, a membrane-permeable sequence (MPS), facilitates research on cell adhesion [1].

st-Ht31, a cell-permeable stearated peptide derived from the amphipathic helix domain of A-kinase anchoring proteins (AKAPs), effectively binds protein kinase A (PKA), impacting PKA's cellular interactions without altering its activity. Specifically, at a 50 µM concentration, it reduces PKA's membrane anchoring in BHK-21 fibroblast reporter assays. Moreover, st-Ht31 at concentrations of 1 and 3 µM decreases both capacitance and hyperactivation in mouse sperm, thereby inhibiting in vitro fertilization. Additionally, at 50 µM, this compound facilitates cholesterol export in BHK-21 cells and RAW 264.7 macrophages expressing ATP-binding cassette transporter 1 (ABCA1), showcasing its multifaceted cellular impacts.

HBpep-SA acetate is a cell membrane-permeable peptide aggregate that undergoes phase separation and forms stable droplets in acidic environments with pH below 6.5, enabling efficient delivery of biomolecules (such as therapeutic peptides and enzymes) and serving as a carrier for mRNA-based vaccines.
