NUPL2 (Nucleoporin Like 2) is a gene encoding a protein component of the nuclear pore complex (NPC). The nuclear pore complex is a massive protein assembly embedded in the nuclear envelope that regulates all nucleocytoplasmic transport, controlling the movement of proteins, RNA, and other molecules between the nucleus and cytoplasm. NUPL2 is specifically involved in the formation, maintenance, and function of the nuclear pore complex, playing essential roles in cellular homeostasis. Dysregulation of nucleocytoplasmic transport has been increasingly recognized as a contributing factor in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), where abnormal protein aggregates can disrupt nuclear pore function and lead to cellular stress.

The NPC is a massive protein complex embedded in the nuclear envelope that controls the movement of molecules between the nucleus and cytoplasm. NUPL2 is involved in the formation and maintenance of the nuclear pore complex, playing a role in the transport of proteins, RNA, and other molecules critical for cellular function. Dysregulation of nucleocytoplasmic transport has been implicated in several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and Huntington's disease, where abnormal protein aggregates can disrupt nuclear pore function.
NUPL2 is ubiquitously expressed, with high expression in tissues with high metabolic activity, including the brain. In neurons, NUPL2 is localized to the nuclear envelope, where it contributes to nuclear pore complex function.
