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

This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.
