In the evolving field of biochemical researc Kisspeptins: a multifunctional peptide system with a role in h, the KP 54 peptide—often referred to in scientific literature as Kisspeptin-54 (human) or Metastin (1-54)—has garnered significant interest. As someone who follows advancements in peptide science, I have foun by XA de Tassigny·2017·Cited by 65—KP-54andKP-10 have been used clinically to stimulate the reproductive axis of men and women and they both show physiological effects. Our data Read more d that understanding the distinction between various members of the kisspeptin (KP) family of peptides is essential for appreciating their unique roles in biological systems.
Understanding the KP 54 Peptide Structure
The KP 54 molecule is a 54 amino acid peptide encoded by the *KISS1* gene. It is categorized as an endogenous peptide in human, mouse or rat systems. Unlike smaller variants like KP-10, KP-54 is frequently highlighted for its unique structural stability. Research indicates that KP-54 is renowned for its favorable pharmacokinetic attributes, including enhanced stability and an extended duration of action *in vivo* compared to its shorter counterparts.
When discussing peptides of this nature, researchers often point to the GPR54, which is a G protein-coupled receptor that serves as the primary binding site for these ligands. The affinity of Kisspeptin-54 (human) for these receptors—with Ki values often cited in the low nanomolar range (approximately 1.45 nM for human receptors)—demonstrates the high specificity of this peptide.
Scientific Observations and Functional Insights
The interest in KP 54 extends beyond simple structural analysis. Historically, this Kisspeptin-54(human) was identified fo Kisspeptin r its potential role in cellular regulation, specifically regarding its ability to act as a tumor metastasis suppressor.
Furthermore, the scientific community has explored how Kisspeptins regulate the mammalian reproductive axis. This is achieved through the interaction between the hypothalamic neuropeptide and the downstream signaling pathways that influence hormone secretion. Because Kisspeptin is a critical regulator of normal reproductive function, it remains a focal point for those studying the Kisspeptin/GPR54 system and how it bridges the gap between various physiological feedback mechanisms.
In addition to its reproductive associations, experimental studies have suggested that KP54 attenuated oxidative stress, neuronal apoptosis and neurobehavioral impairments in specific models. Observations have also noted that KP-10, KP-13, and KP-54 acted as vasoc Kisspeptin-54 (27-54) is a peptide. This product is made to order.
