The Human Respiratory Syncytial Virus (HSV) is a major cause of lower respiratory tract infection. Deadly to newborn babies, new therapies are being developed to keep infants alive. By understanding how dynamic structural changes in the Fusion F Glycoprotein reveal and hide binding sites, new therapies more effectively target RSV and prevent infection.

“Ebolavirus (EBOV) is a highly virulent pathogen capable of causing a severe hemorrhagic fever with 50–90% lethality. The EBOV glycoprotein (GP) is the only virally expressed protein on the virion surface and is critical for attachment to host cells and catalysis of membrane fusion. Hence, the EBOV GP is a critical component of vaccines as well as a target of neutralizing antibodies and inhibitors of attachment and fusion. The crystal structure of the Zaire ebolavirus GP in its trimeric, prefusion conformation (3 GP1 plus 3 GP2) in complex with a neutralizing antibody fragment, derived from a human survivor of the 1995 Kikwit outbreak, was recently determined.
This is the first near-complete structure of any filovirus glycoprotein. The overall molecular architecture of the Zaire ebolavirus GP and its role in viral entry and membrane fusion are discussed in this article.” — NCBI Citation
Structural Mechanisms of Nucleosome Recognition by Linker Histones
“The EBOV envelope GP directly mediates binding of the virion to the host cell. A number of cellular factors, including DC-SIGN/L-SIGN [68,69], LSECtin [70,71], hMGL , β-integrins  and Tyro3 family receptors , have been implicated as attachment factors, however, none of these proteins individually are necessary and sufficient for viral entry. Hence, a critical cell-surface receptor responsible for EBOV attachment has yet to be identified, despite significant effort. It appears that EBOV enters through a receptor-mediated endocytotic mechanism, but it is still unclear whether clathrin-, caveolae- or cholesterol-dependent processes are used. Recombinant systems using pseudotyped retro-virus particles with ZEBOV GP and live virus studies using chemical inhibitors of clathrin- and caveolae-mediated endocytosis point to the use of caveolae and clathrin in EBOV entry [75,76]. However, cells lacking in caveolae can still be infected with EBOV .” – NCBI Citation
This is a 3D print of x-ray crystallography datasets PDB IDs: 3CSY, 2EBO The protein surface color coding is defined by the glycoprotein's Hydrophobicity.

EGFR is an important protein for a variety of different types of oncology. It is important for the development of mammary glands. It's ligands ( TGF-α, and heregulin) play such vital roles in development, that in the absence of hormone signals can still induce ductal and lobuloalveolar development.
EGFR is located on the surface of cells throughout the body. When activated by different cytokines, receptors dimerize and initiates downstream signaling via its intracellular tyrosine kinase domains.
Dimerization stimulates the intracellular tyrosine kinase domains. This begins a process where several tyrosine residues are autophosphorylated. (Y992, Y1068, Y1148, Y1173 ). Downstream signaling following this includes MAPK, Akt, and HNK pathways. These lead to both DNA synthesis and cellular proliferation. If this process becomes uncontrolled, an unfortunate disease state develops.
Inactive EGFR 3D Animation
Tyrosine Kinases exist in two distinct states, inactive and active. Inactive states are marked by their contracted a-loop with a closed N-lobe. When closed, the ATP binding pocket of the tyrosine kinase is blocked. and tyrosine residues are protected from phosphorylation. In the active state, the a-loop is extended with an open N-lobe revealing the ATP-binding pocket of the kinase.
Role in Health and Disease
Mutations in EGFR lead to overexpression of proteins and different types of cancers as cells continually and proliferate. Advancements in drug design allow for the continued binding of small molecules despite mutations. These compounds prevent kinase phosphorylation and down-regulate EGFR signals.
Mutant Active EGFR 3D Animation
Cancer isn't the only issue. Psoriasis, eczema, and atherosclerosis are all implicated in over-expression of EGFR. This is not well understood yet, but likely due to over-expression of inflammatory cytokines that initiate EGFR phosphorylation.
A common strategy of small molecule inhibitors is to identify receptors and examine their intra-cellular kinase domains. In many cases, this prevents aberrant behaviors in the receptor and mitigate the develop of disease. An easy target for this inhibition process is the kinase domain's ATP binding pocket. It has a high affinity for its ligand and phosphorylation of its tyrosine residue a requirement for signal propagation.
