This property is often attributed to their amino acid composition, which typically exhibits a high abundance of positively charged residues, such as lysine or arginineCell-penetrating peptides (CPPs) aresmall (10–30 residues in length), often positively charged sequences of amino acids, which were also termed.. Polyarginine, in particular, is a prominent example of such a peptide. It is frequently described as a cationic cell penetrating peptide (CPP), with specific variants like Cys-Arg8 and Arg8 (also known as polyarginine) being extensively studied for their cargo delivery potentialFull article: Polyarginine and PEG-AEYLR comodified .... These peptides can be as small (10–30 residues in length), often positively charged sequences of amino acids, making them efficient molecular carriers.

The mechanism by which these peptides facilitate cellular entry is a subject of ongoing research.2017年11月24日—Polyarginines are well known for their ability to enhance cell penetration. ... Preparation of cell-permeable Cre recombinase by expressed protein ... While some studies suggest direct passage through the lipid membrane, others indicate alternative pathways. For instance, Arginine-rich cell-penetrating peptides have been shown to enter cells through mechanisms that do not involve directly traversing the lipid bilayer, but rather by passively entering vesicles.

(2019) indicates that polyarginine (R8) peptides penetrate the membrane through a water pore in the membrane, with transmembrane efficiency being notably improved by certain modifications. Furthermore, the oxidation state of the cell can influence the cytosolic penetration of linear polyarginine peptides, as demonstrated by Wang et al. (2016).

The applications of polyarginine cell penetrating peptides are diverse and expanding. They are utilized as cellular delivery tools, enabling the transport of a wide range of molecules, including proteins, peptides, DNA, and RNA.Polyarginine Cell-Penetrating Peptides Bind and Inhibit ... For example, the integration of a polyarginine cell penetrating peptide with a GRP78-targeting peptide has shown promise for selective and effective peptide-based siRNA transfection.Polyarginine 8R The Argi system, developed by Bartnicki et al. (2017), is a testament to the utility of arginine-rich sequences, offering a novel affinity chromatography tool for the purification of CPP-tagged proteins.Polyarginine - an overview

The length and composition of polyarginine sequences significantly impact their cellular uptake and functionality. While polyarginine peptides composed of nine arginine amino acids (Arg-9) have been shown to translocate across cells very efficiently (Herce et al., 2009), research also explores shorter sequences. For instance, poly-arginine peptides of varying lengths are being investigated for their potential in therapeutic applications. However, it's important to note that in some contexts, poly-arginine peptides are actually quite limited in the degree of neuroprotection conferred, highlighting the need for careful optimization based on the intended application作者：G Hilan·2025·被引用次数：2—The integration of apolyarginine cell penetrating peptidewith a GRP78-targeting peptide provides selective and effective peptide-based ....
