DDX1 is a member of the DEAD-box RNA helicase family with characteristic motifs including the Q motif, motif I (AxxGxGKT), motif II (DEAD), and motif VI. The protein contains two RecA-like domains connected by a flexible linker.
DDX1 functions as an ATP-dependent RNA helicase:
The study of Ddx1 Protein 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 DDX1 Protein 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 DDX1 Protein 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 DDX1 Protein 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.
