Nup100p

Nup100p is a protein found in yeast that plays a crucial role in the nuclear pore complex (NPC). The NPC is a large protein assembly that spans the nuclear envelope, regulating the transport of molecules between the nucleus and the cytoplasm. Nup100p is a component of the nuclear basket, a structure located on the nuclear side of the NPC. It is a highly conserved protein, meaning it is found in many different organisms with similar structures and functions.

The precise function of Nup100p within the NPC is still an active area of research. However, studies suggest it contributes to the structural integrity of the nuclear basket and may be involved in the regulation of nucleocytoplasmic transport. It is known to interact with other NPC proteins, forming a complex network that facilitates the selective passage of molecules. Mutations or disruptions in Nup100p have been shown to affect NPC function and can lead to various cellular defects in yeast. Understanding Nup100p's role is important for comprehending the overall mechanism of nuclear transport and the maintenance of nuclear organization.
