**Background of CNDP1 Recombinant Protein**
CNDP1 (Carnosine Dipeptidase 1), also known as carnosine dipeptidase 1 or serum carnosinase, is a zinc-dependent metallopeptidase encoded by the *CNDP1* gene. This enzyme primarily hydrolyzes dipeptides such as carnosine and homocarnosine into their constituent amino acids (β-alanine/histidine or GABA/histidine). CNDP1 is synthesized as a precursor protein and processed into a mature, secreted enzyme, predominantly expressed in the kidney, liver, and brain. Its role in regulating bioactive dipeptides links it to cellular processes like antioxidant defense, neurotransmission, and pH buffering.
Clinically, CNDP1 has gained attention due to genetic polymorphisms associated with susceptibility to diabetic nephropathy (DN). A specific trinucleotide repeat (5-8 leucine repeats) in the *CNDP1* gene correlates with reduced enzyme activity and improved renal outcomes in diabetic patients, suggesting a protective role against DN progression. Dysregulation of CNDP1 is also implicated in neurological disorders (e.g., epilepsy, Alzheimer’s) and cancer, where altered carnosine metabolism may influence tumor microenvironment dynamics.
Recombinant CNDP1 protein, produced via heterologous expression systems (e.g., mammalian or bacterial cells), enables mechanistic studies of its enzymatic activity, substrate specificity, and interactions. It serves as a critical tool for developing diagnostic assays, screening inhibitors, or exploring therapeutic strategies targeting CNDP1-related pathways. By providing a purified, functional form of the enzyme, recombinant CNDP1 facilitates research into its biological roles and potential clinical applications in metabolic and degenerative diseases.
