What Are Peptides? Definition: Short polymers of amino acids linked by peptide bonds, smaller than proteins. Key roles in the body: Hormones (e.g., insulin, GLP-1) Neurotransmitters (e.g., oxytocin, vasopressin) Growth factors (e.g., BPC-157, IGF-1) Signaling molecules regulating metabolism, immunity, and repair

Klotho is a transmembrane glycoprotein encoded by the KLOTHO gene and structurally characterized by a short intracellular domain and a large extracellular region containing two internal repeat domains, KL1 and KL2. These domains share sequence homology with family 1 glycosidases, although classical glycosidase enzymatic activity has not been clearly demonstrated. Post-translational processing by membrane-associated proteases such as ADAM10 and ADAM17 enables the extracellular domain of Klotho to be released into circulation and biological fluids, generating soluble forms that exhibit distinct biochemical properties from the membrane-bound protein. Expression analyses indicate that Klotho is most abundantly localized in renal distal convoluted tubules and the choroid plexus, with additional expression observed in the proximal tubule, parathyroid gland, reproductive tissues, vascular adventitia, and selected regions of the central nervous system. Beyond α-Klotho, homologous β- and γ-K...
