NUP155 and hydrops fetalis: Therefore, in this work, to study the NPC in HF patients, we performed a mapping of this complex through the study of different representative proteins that at different levels of this structure make up: transmembrane ring (NDC1), inner ring (Nup155), outer ring (Nup160), FG nucleoporins (Nup153), linker nucleoporins (Nup93) and the periphery nucleoporins of the nuclear face (TPR).
