Target type: biologicalprocess
Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of amyloid precursor protein (APP), the precursor of amyloid-beta. [GOC:go_curators]
Positive regulation of amyloid precursor protein biosynthetic process refers to the mechanisms that enhance or stimulate the production and maturation of amyloid precursor protein (APP). APP is a transmembrane protein that undergoes complex processing within the cell, leading to the formation of amyloid-beta (Aβ) peptides.
APP biosynthesis begins with the transcription and translation of the APP gene, resulting in the production of a precursor protein. This precursor undergoes several modifications, including glycosylation and proteolytic cleavage by enzymes called secretases.
The key secretases involved in APP processing are β-secretase (BACE1) and γ-secretase. BACE1 cleaves APP within its ectodomain, generating an N-terminal fragment called sAPPα and a C-terminal fragment called C99. C99 is further cleaved by γ-secretase, which can release either Aβ peptides or a soluble APP fragment called AICD.
Positive regulation of APP biosynthesis can occur at multiple levels, including:
- Transcriptional regulation of the APP gene: Various factors can enhance the transcription of the APP gene, leading to increased production of APP mRNA and ultimately, APP protein.
- Post-translational modifications: Modifications such as glycosylation can influence APP stability and processing.
- Secretases activity: Regulation of BACE1 and γ-secretase activity can impact APP processing and Aβ production.
Disregulation of APP biosynthesis and processing is implicated in Alzheimer's disease, a neurodegenerative disorder characterized by the accumulation of Aβ plaques in the brain. Therefore, understanding the mechanisms involved in the positive regulation of APP biosynthetic process is crucial for developing therapeutic strategies to target Aβ production and potentially alleviate Alzheimer's disease pathology.'
