CDR1 (Cerebellar Degeneration-Related Protein 1), also known as CDR1AS, is a circular RNA (circRNA) that functions as a sponge for miR-7. Unlike typical genes, CDR1AS is a stable circular RNA expressed primarily in the brain. It regulates synaptic function and neuronal gene expression by sequestering microRNAs, particularly miR-7, which targets multiple genes involved in neurodegeneration.
CDR1AS has been implicated in neurodegenerative processes:
CDR1AS is predominantly expressed in the brain, particularly in the cerebral cortex, hippocampus, and cerebellum. It is enriched in synapses where it regulates local miRNA activity. Expression is highest during early development and remains substantial in adult neurons.
The study of Cdr1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.

The CDR1 Gene is involved in various cellular processes in the nervous system. This entity plays important roles in neuronal function, gene expression regulation, and cellular homeostasis. Dysfunction has been implicated in neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis.
The CDR1 Gene participates in multiple molecular pathways critical for neuronal health. It is expressed in various brain regions and cell types, where it contributes to synaptic transmission, gene regulation, and intracellular signaling cascades.
Alterations in CDR1 Gene expression or function have been associated with several neurodegenerative conditions. Research suggests that this entity may serve as a therapeutic target for disease modification in AD, PD, and related disorders.
