Step-by-step guide to nuclear pore complex assembly

Science & Technology EMBL Heidelberg researchers and their collaborators reveal how the nuclear pore complex, one of the biggest molecular machines in eukaryotic cells, is assembled one protein at a time.

Party at the nucleus?

Science & Technology The nucleus of this cell fluoresces in bright green thanks to GFP-labelled nucleoporin proteins. EMBL scientists use engineered nucleoporins as 3D reference standards to improve super-resolution microscopy.

Nuclear pores in their natural context

Science & Technology Scientists from the Beck group have studied the 3D structure of nuclear pores in budding yeast. They show how the architecture of the nuclear pore complex differs inside cells compared to its form observed in vitro studies.
