Nucleoporin genes in human diseases.

Area of Science:

• Molecular Biology
• Cell Biology
• Genetics

Background:

• Nuclear pore complexes (NPCs) are essential cellular machinery regulating transport across the nuclear envelope.
• NPCs are assembled from numerous protein subunits known as nucleoporins (NUPs).
• Dysregulation of NUPs is implicated in various pathological conditions.

Purpose of the Study:

• To provide a comprehensive overview of nucleoporins (NUPs).
• To discuss the genes encoding NUPs, their cellular localization, and functions within the NPC.
• To explore the involvement of NUPs in human diseases, including neoplastic and non-neoplastic conditions.

Main Methods:

• Literature review and synthesis of existing research on nucleoporins.
• Analysis of NUP gene information, including structure and regulation.
• Examination of functional studies detailing NUP roles in NPC assembly and transport.
• Review of clinical data linking NUP alterations to human diseases.

Main Results:

• Nucleoporins (NUPs) are diverse proteins crucial for NPC structure and function.
• Specific NUPs exhibit distinct localization patterns within the NPC, influencing transport selectivity.
• Alterations in NUP genes are associated with the pathogenesis of various cancers and other diseases.
• NUPs play critical roles in maintaining nuclear transport homeostasis.

Conclusions:

• Nucleoporins (NUPs) are integral components of the nuclear pore complex with vital roles in cellular function.
• Understanding NUPs, their genes, and functions is crucial for deciphering their involvement in human diseases.
• Targeting NUPs presents potential therapeutic strategies for diseases linked to NPC dysfunction.
