Research progress of heterogeneous nuclear rib nucleoprotein A2/B1 and neurodegenerative disease / 中国医师杂志

ABSTRACT

Heterogeneous nuclear rib nucleoproteins belong to a class of RNA-binding proteins and possess highly conserved structures. Among them, the heterogeneous nuclear rib nucleoprotein A2/B1 (heterogeneous nuclear rib nucleoprotein A2, hnRNPA2/B1) is involved in many processes such as transcription and translation. In recent years, in the field of neurodegenerative diseases, it has been found that hnRNPA2/B1 promotes the accumulation of fibrin in the cytoplasm and participates in the formation of stress granules in neurons, which involves a variety of processes related to cognitive function, and is closely related to neurodegenerative diseases such as amyotrophic lateral sclerosis, frontotemporal dementia, Alzheimer′s disease and so on. This article reviews the related research, summarizes the important role and mechanism of hnRNPA2/B1 in neurodegenerative diseases, and provides help for the diagnosis and treatment of neurodegenerative diseases in the future.
