NUPL2 (Nucleoporin Like 2) is a nucleoporin protein encoded by the NUPL2 gene, located on chromosome 7p15.3. The protein is a component of the nuclear pore complex (NPC), one of the largest protein complexes in the cell, composed of approximately 30 different nucleoporins. NUPL2 has a molecular weight of approximately 55 kDa and is localized to the nuclear envelope where it participates in the formation and maintenance of the nuclear pore complex. The NPC serves as the sole gateway for regulated transport between the nucleus and cytoplasm, controlling the passage of proteins, RNA, ribosomes, and other molecules. NUPL2 contributes to the structural integrity of the NPC and participates in nucleocytoplasmic transport by interacting with transport receptors. Dysfunction of NUPL2 and other nucleoporins has been implicated in several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS).
NUPL2 is a nucleoporin protein that contains multiple domains involved in protein-protein interactions within the nuclear pore complex (NPC). The NPC is composed of approximately 30 different nucleoporins, each contributing to its structure and function. NUPL2 is involved in the formation of the nuclear pore scaffolding.
NUPL2 is a component of the nuclear pore complex (NPC), one of the largest protein complexes in the cell. The NPC regulates all transport between the nucleus and cytoplasm, controlling the passage of proteins, RNA, ribosomes, and other molecules. NUPL2 contributes to the structural integrity of the NPC and participates in nucleocytoplasmic transport by interacting with transport receptors. This function is essential for gene expression regulation, protein synthesis, and cellular homeostasis.
Dysfunction of NUPL2 and other nucleoporins has been implicated in several neurodegenerative diseases:
While NUPL2 itself is not a direct therapeutic target, the nuclear pore complex is being explored as a potential therapeutic target for neurodegenerative diseases. Strategies to improve nuclear pore function and restore nucleocytoplasmic transport are under investigation.
