In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Cell–cell fusogens: Cell–cell fusogens are glycoproteins that facilitate the fusion of cell to cell membranes. Cell-cell fusion is critical for the merging of gamete genomes and development of organs in multicelluar organisms.RNA transfection: RNA transfection is the process of deliberately introducing RNA into a living cell. RNA can be purified from cells after lysis or synthesized from free nucleotides either chemically, or enzymatically using an RNA polymerase to transcribe a DNA template.Tumor-associated glycoprotein: Tumor-associated glycoproteins (TAGs) are glycoproteins found on the surface of many cancer cells. They are mucin-like molecules with a molar mass of over 1000 kDa.Cryptic self epitopes: In immunology, cryptic self epitopes are a source of autoimmunity.White spot syndrome: White spot syndrome virus is the lone virus (and type species) of the genus Whispovirus (white spot), which is the only genus in the family Nimaviridae.

The C-C motif chemokine receptor CCR5 is involved in the process by which HIV, the virus that causes AIDS, enters cells.Membrane protein: Membrane proteins are proteins that interact with biological membranes. They are one of the common types of protein along with soluble globular proteins, fibrous proteins, and disordered proteins.Monoclonal antibody therapyMultiple cloning site: A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites - a standard feature of engineered plasmids. Restriction sites within an MCS are typically unique, occurring only once within a given plasmid.HIV Vaccine Trials Network: The HIV Vaccine Trials Network (HVTN) is a non-profit organization which connects physicians and scientists with activists and community educators for the purpose of conducting clinical trials seeking a safe and effective HIV vaccine. Collaboratively, research professionals and laypeople review potential vaccines for safety, immune response, and efficacy.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Hepatitis B virus precore mutant: A precore mutant is a variety of hepatitis B virus that does not produce hepatitis B virus e antigen (HBeAg). These mutants are important because infections caused by these viruses are difficult to treat, and can cause infections of prolonged duration and with a higher risk of liver cirrhosis.CXC chemokine receptors: CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors, a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times.Vesicular stomatitis virus: Vesicular stomatitis Indiana virus (VSIV) (often still referred to as VSV) is a virus in the family Rhabdoviridae; the well-known rabies virus belongs to the same family. VSIV can infect insects, cattle, horses and pigs.Generalized vaccinia: Generalized vaccinia is a cutaneous condition that occurs 6-9 days after vaccination, characterized by a generalized eruption of skin lesions, and caused by the vaccinia virus.Reuben Rickard: Reuben Rickard (August 20, 1841 – February 28, 1896) was a mining engineer who served as President of the Town Board of Trustees in Berkeley, California from 1891 to 1893, and again for about one month during 1895.Sindbis virusGammaretrovirus core encapsidation signalLow-voltage electron microscope: Low-voltage electron microscope (LVEM) is an electron microscope which operates at accelerating voltages of a few kiloelectronvolts or less. While the low voltage electron microscopy technique will never replace conventional high voltage electron microscopes, it is quickly becoming appreciated for many different disciplines.Natural transfer: The natural transfer (hypothesis or theory), in reference to the HIV/AIDS pandemic, states that humans first received HIV by contact with primates, presumably from a fight with a Chimpanzee during hunting or consumption of primate meat, and became contaminated with simian immunodeficiency virus (SIV). According to the 'Hunter Theory', the virus was transmitted from a chimpanzee to a human when a bushmeat hunter was bitten or cut while hunting or butchering an animal.FERM domain: In molecular biology, the FERM domain (F for 4.1 protein, E for ezrin, R for radixin and M for moesin) is a widespread protein module involved in localising proteins to the plasma membrane.Epitope mapping: Epitope mapping is the process of experimentally identifying the binding sites, or ‘epitopes’, of antibodies on their target antigens. Identification and characterization of the binding sites of antibodies can aid in the discovery and development of new therapeutics, vaccines, and diagnostics.Ranavirus: Ranavirus is a genus of viruses, in the family Iridoviridae. There are four other genera of viruses within the family Iridoviridae, but Ranavirus is the only one that includes viruses that are infectious to amphibians and reptiles.Database of protein conformational diversity: The Database of protein conformational diversity (PCDB) is a database of diversity of protein tertiary structures within protein domains as determined by X-ray crystallography.
