SMILES: CC(C)C[C@@H](C(O)=O)NC([C@H](CCCCN)NC([C@H](CCC(O)=O)NC([C@@H](NC([C@H]([C@H](O)C)NC([C@H]([C@@H](C)CC)NC([C@H]([C@@H](C)CC)NC([C@@H](N)CO)=O)=O)=O)=O)CC1=CC=CC=C1)=O)=O)=O
Biological Activity: OVA-T4 Peptide (SIITFEKL; OVA (257-264) Variant) is a modified peptide ligand of OVA 257-264 that binds to mouse OT-I TCR with Kd = 1.22 μM, acts as a weaker agonist than the parental N4 peptide to modulate the strength of antigen-presenting cell-T lymphocyte interactions, and alters the amplitude of cytokine responses and NFAT1, p-Erk, and NF-κB signaling responses. OVA-T4 Peptide can be used for research on colon cancer and ovarian cancer[1][2][3][4][5][6][7].
