Architecture and composition of plant nucleopore complexes, comparisons with putative homologs across kingdoms

Nucleopore Complexes are intricate protein assemblies composed of diverse nucleoporins, which serve as crucial mediators for the bidirectional movement of molecules between the nucleus and cytosol. These nucleoporins share both structural and functional characteristics across yeast, mammals, and pla...

Description
Summary:Nucleopore Complexes are intricate protein assemblies composed of diverse nucleoporins, which serve as crucial mediators for the bidirectional movement of molecules between the nucleus and cytosol. These nucleoporins share both structural and functional characteristics across yeast, mammals, and plants. This review highlights these shared architectural elements and further examines specific nucleoporins. A particular emphasis is placed on the putative homologs yeast NUP1, human NUP153, and plant NUP136, and their shared involvement in critical processes such as developmental coordination, gene regulation, and immune responses. Despite variations in their amino acid sequences, these proteins exhibit a notable degree of structural conservation, supporting a convergent evolution that would underlie their similar functionalities.
