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.
