Nucleoporin 54

Nucleoporin 54 (NUP54) is a protein that in humans is encoded by the NUP54 gene. It is a component of the nuclear pore complex, a structure that regulates the movement of molecules between the nucleus and the cytoplasm.

Function

NUP54 is a member of the nucleoporin family. Nucleoporins are proteins that play crucial roles in the nuclear pore complex structure and function. NUP54 is located on the cytoplasmic face of the nuclear pore complex and is involved in the nuclear export of proteins and RNAs.

Clinical significance

Mutations in the NUP54 gene have been associated with various diseases. For example, a mutation in this gene has been linked to Triple A syndrome, a rare autosomal recessive disorder characterized by adrenal insufficiency, alacrima, and achalasia.

Structure

The NUP54 protein is composed of 475 amino acids and has a molecular weight of approximately 54 kDa. It contains a phenylalanine-glycine (FG) repeat region, which is a common feature of many nucleoporins and is thought to be involved in the transport of molecules across the nuclear pore complex.

Interactions

NUP54 has been shown to interact with several other proteins, including NUP62, NUP58, and NUP45. These interactions are thought to be important for the assembly and function of the nuclear pore complex.
