Full-length integrin cytoplasmic tails can be difficult to work with due to poor solubility, limiting the ability to form stable complexes for structural or functional studies作者：B Garcı́a-Alvarez·2003·被引用次数：625—Consistent with our NMR data on the full-lengthintegrin tail, asynthetic peptide(WDTGENPIYKSAV) derived from the β1tailhas been shown to bind to talin and .... The use of synthesized peptides offers a solution, as their properties can be modulated during synthesis, and they can often be designed to be soluble in aqueous buffers, facilitating experimental manipulation. For example, studies have investigated the limited solubility of the full-length $\beta_3$ tail, highlighting the utility of soluble peptide fragments.
The development of integrin tail synthesized peptide soluble entities holds promise for various applications, particularly in the field of drug discovery and targeted therapies. By designing peptides that mimic or antagonize the function of integrin tails, researchers aim to modulate integrin activity for therapeutic benefit. For instance, synthetic peptides have been engineered to target specific integrin subtypes, such as $\alpha_v\beta_3$ and $\alpha_v\beta_6$, which are often overexpressed in tumors. These peptides can be used as probes for diagnostic imaging or as therapeutic agents to inhibit tumor growth or metastasis.
Furthermore, the study of these peptides contributes to a deeper understanding of integrin activation mechanisms. Researchers are exploring how different sequences within the integrin tail influence binding to effector proteins like talin and kindlin, and how these interactions lead to conformational changes that enhance ligand binding and signal transduction.Interface Immobilization Chemistry of cRGDbased Peptides ...
