This review is devoted to annulate lamellae, a specific compartment of endoplasmic reticulum that occurs,
presumably, in actively growing and rapidly dividing cells (oocytes, embryonic and tumor cells). We summarized both earlier and
recent data on the dustribution of annulate lamellae in various cell types, on their morphology, and the distribution of
interaction with intracellular structures at various treatments. As the annulate lamellae contain cytoplasmic pore complexes,
a special attention was paid to their relation with nuclear pores. Possible functions of the annulate lamellae in intracellular
processes and, particularly, in nuclear envelope assembly, are discussed.
