tyrosine kinase peptide 1

Tyrosine Kinase Peptide 1 is a control substrate peptide used in c-Src assay.

Lyn Peptide Inhibitor TFA is a powerful, cell-permeable inhibitor specifically targeting the Lyn-coupled IL-5 receptor signaling pathway, without affecting alternative signaling pathways. It effectively prevents Lyn activation and impedes the association between Lyn tyrosine kinase and the βc subunit of IL-3 GM-CSF IL-5 receptors. This compound is utilized in the investigation of asthma, allergic reactions, and various eosinophilic conditions [1].

P60v-src(137-157) is a synthetic peptide that inhibits the tyrosine kinase activity of p60 v-src, with an IC50 of 7.5 μM [1] [2].

A11, a cell-penetrating peptide, integrates the HIV-1 Tat protein transduction domain with an 11-amino acid segment from the annexin A1 N-terminus (residues 20-30). This compound disrupts the interaction between annexin A1 and the Eph receptor tyrosine kinase A2 (EphA2), leading to enhanced EphA2 ubiquitination in HK1 nasopharyngeal carcinoma (NPC) cells. At a concentration of 10 µM, A11 curtails proliferation, migration, and invasion of HK1 and 5-8F NPC cells. Furthermore, A11 demonstrably diminishes tumor volume in mouse xenograft models of 5-8F and HK1 NPC in vivo.
