WebThe first step in the generation of the amyloid-beta peptide (Abeta) deposited in the brains of patients with Alzheimer's disease (AD) is the processing of the larger Abeta precursor protein (APP) by an integral membrane aspartyl protease named the beta-site APP-cleaving enzyme (BACE). We present the genomic organization of the BACE gene. BACE … Web25 jul. 2024 · To Gene. A gene is a stretch of DNA that contains the instructions for making or regulating a specific protein. Genes that make proteins are called protein-coding genes. In order to make a protein, a molecule closely related to DNA called ribonucleic acid (RNA) first copies the code within DNA.
