**** is a human gene whose product dNA Damage Regulated Autophagy Modulator 2 (DRAM2)** is a lysosomal protein that plays a critical role in autophagy and cell survival under stress conditions. DRAM2 is a member of the DRAM (Damage-Regulated Autophagy Modulator) family, which includes DRAM1 and DRAM2, both involved in p53-mediated autophagy induction. Variants in have been implicated in Alzheimer's Disease, Parkinson's Disease, Cancer. This page covers the gene's normal function, disease associations, expression patterns, and key research findings relevant to neurodegeneration.
DNA Damage Regulated Autophagy Modulator 2 (DRAM2) is a lysosomal protein that plays a critical role in autophagy and cell survival under stress conditions. DRAM2 is a member of the DRAM (Damage-Regulated Autophagy Modulator) family, which includes DRAM1 and DRAM2, both involved in p53-mediated autophagy induction.
DRAM2 functions as a positive regulator of autophagy by:
DRAM2 is primarily localized to:
The protein contains multiple transmembrane domains that target it to lysosomal compartments.
DRAM2 expression is altered in Alzheimer's disease brains. The protein participates in:
DRAM2 is implicated in Parkinson's disease through:
While primarily studied in neurodegeneration, DRAM2 also has roles in:
DRAM2 exhibits broad expression across tissues:
In the brain, DRAM2 is expressed in neurons and glial cells, with elevated expression under cellular stress conditions.
DRAM2 represents a potential therapeutic target for:
Small molecules that upregulate DRAM2 expression may promote autophagy and protect against neurodegeneration.
DRAM2 is directly regulated by the tumor suppressor protein p53, one of the key pathways linking DNA damage to autophagy:
While DRAM2 is not a major GWAS hit for Alzheimer's or Parkinson's disease, evidence suggests it may play a modifier role:
DRAM2 is a ~237 amino acid protein with:
Recent research focuses on:
