Our cells separate the process of protein synthesis into two compartments: DNA is transcribed to mRNA in the nucleus, while mRNA is translated to protein in the cytoplasm. This separation allows additional regulatory steps to be added to the process, such as capping and splicing of the mRNA. The nuclear pore complex (NPC), a huge channel embedded in the nuclear envelope, connects these two separated processes, providing two-way transport of nucleic acids and proteins between the nucleus and cytoplasm.
PDB-101 highlights how these PDB structures have increased our understanding of HIV in an interactive animation and a poster.
PDB-101 helps teachers, students, and the general public explore the 3D world of proteins and nucleic acids. Learning about their diverse shapes and functions helps to understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease to biological energy.
Why PDB-101? Researchers around the globe make these 3D structures freely available at the Protein Data Bank (PDB) archive. PDB-101 builds introductory materials to help beginners get started in the subject ("101", as in an entry level course) as well as resources for extended learning.
