Research indicates that gomesin operates through mechanisms that differ from typical pore-forming antimicrobial peptides, instead inducing lipid accumulation and impacting cell proliferation.
Isolated from the venom of *Acanthoscurria gomesiana*, gomesin is characterized as a cationic antimicrobial peptide.作者：PI Silva·2000·被引用次数：319—Gomesin has a molecular mass of 2270.4 Da, with 18 amino acids, including a pyroglutamic acid as the N terminus, a C-terminal arginine α-amide, and four ... It is an 18-residue peptide rich in cysteine, featuring a pyroglutamic acid at the N-terminus and an arginine α-amide at the C-terminus. Its molecular mass is approximately 2270.4 Da.Peripheral Antimicrobial Peptide Gomesin Induces ... The cationic nature of gomesin (z = +6) plays a crucial role in its interaction with biological membranes.
Unlike many antimicrobial peptides that function by creating pores in cell membranes, gomesin exhibits a distinct mechanism. Studies suggest that gomesin does not disrupt bacterial membranes by forming stable transmembrane pores. Instead, its interaction with membranes leads to the accumulation of lipidsStructure-Activity Relationship of the AntimicrobialPeptide Gomesin: the Role ofPeptideHydrophobicity in Its Interaction with Model Membranes.

The antimicrobial peptide gomesin demonstrates significant potential in combating microbial infections. Beyond its antimicrobial properties, gomesin and its derivatives have shown promising antiproliferative and cytotoxic activities against cancer cells. For instance, gomesin peptides have been observed to prevent proliferation and induce cell death in devil facial tumour disease cells.
Furthermore, modified versions like cyclic gomesin (cGm) have been developed.作者：X Liu·2023·被引用次数：5—Gomesinis a cationic antimicrobial peptidewhich is isolated from the haemocytes of the Brazilian tarantula Acanthoscurria gomesiana and can be produced ... Cyclic gomesin internalizes cells via endocytosis and direct membrane permeation, showcasing enhanced cellular uptake.作者：TM Domingues·2013·被引用次数：60—Gomesin is a potent cationic antimicrobial peptide(z = +6) isolated from the Brazilian spider Acanthoscurria gomesiana . The interaction of ... These spider-derived peptides are considered therapeutically promising, targeting specific phospholipid compositions within cells.Effects of the antimicrobial peptide gomesin on the global ... Research into gomesin-like peptides has also revealed more selective antifungal activities compared to the parent gomesin.
Understanding the structure-activity relationship of gomesin is key to optimizing its therapeutic potential. The hydrophobicity of the peptide is a significant factor influencing its interaction with model membranes. Ongoing research focuses on redesigning gomesin analogues, such as cyclic versions, to enhance their potency, selectivity, and pharmacokinetic properties. While gomesin shows promise, further investigation is needed to fully elucidate its therapeutic applications and safety profile.
