Calmodulin is an intracelular target of calcium ions. Once activated by Ca2+ (red), calmodulin interacts with various target proteins such as kinases and phosphatases.. It plays an important role in long-term memory. and muscle contraction. CaM has 4 calcium binding sites. PDB entry 3CLN, 1CFD
Antibodies attacking SARS-CoV-2 virus
Alpha-actinin 2, a protein which crosslinks filamentous actin molecules and titin molecules from adjoining sarcomeres at Z-discs, a function that is modulated by phospholipids. 3d rendering.
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.
