Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.

Immunoglobulin G (IgG) - 3d rendered image. Microbiology illustration the structure of an antibody. The Y-shaped structure. IgG is the most common type of antibody. Hologram view. SEM.

Proteasomes are a large molecular machine that degrade unneeded or damaged proteins that have been tagged with polyubiquitin (yellow). The ubiquitin hydrolase (violet) detaches ubiquitin from the protein, that is unfolded and degraded into small peptides (bottom). Source: PDB entry 5GJQ

3d rendering of ubiquitin is attached to target proteins by a process called ubiquitination

Covid-19 Coronavirus Variants Omicron Delta Gamma Beta Alpha Pandemic Virus Disease Mutation

$3D model of a protein in coloured shades. The surface irregularities are a realistic representation. Proteins play a very important role in human health. Their research is directly related to medicine and drug discovery, and the image symbolises this.\nBeautiful protein structures can be used as journal covers and inserts.\nIt is a work created by CG. Not created by AI.$
