SDKPDMAEIEKFDKSK（Cat No.:I044190）is a synthetic peptide corresponding to a segment of the human heat shock protein 27 (Hsp27), often used in studies involving cellular stress responses, protein-protein interactions, and phosphorylation pathways. The sequence includes acidic (Asp, Glu) and basic (Lys) residues, contributing to its role in modulating molecular chaperone activity and interactions with signaling proteins. Researchers use this peptide to investigate mechanisms of apoptosis, cytoprotection, and neurodegenerative disease progression. Its biochemical properties make it valuable for assays exploring stress-induced signaling cascades and therapeutic strategies targeting heat shock proteins in cancer or inflammation.
