WebApr 11, 2024 · The portal-scaffold complex is believed to nucleate the assembly of herpesvirus procapsids. During capsid maturation, two events occur: scaffold expulsion and DNA incorporation. The portal-scaffold interaction and the conformational changes that occur to the portal during the different stages of cap … WebMar 20, 2024 · Microtubule stabilization drives the extending neurite, yet little is known of the molecular mechanisms whereby extracellular cues regulate microtubule dynamics. Bone morphogenetic proteins (BMPs) play an important role in neuronal differentiation and morphogenesis, and BMP7 in particular induces the formation of dendrites.

WebThe capsid protein has a modular domain organization with an N-terminal arm (NTA) that is important for directing capsid assembly, followed by a shell (S) domain that is important … WebAs one can imagine, assembling 120 protein chains into a perfectly symmetrical shell is a difficult task. PhiX174 uses special scaffolding proteins to ensure that everything ends up in the right place. The capsid and spike proteins spontaneously form pentagonal units, with five copies of each chain.
WebIf the capsid protein's structure could be entirely dedicated to this endeavor, the morphogenetic mechanism would be relatively uncomplicated. However, capsid proteins have had to evolve other functions, such as receptor recognition, immune system evasion, and the incorporation of other structure proteins, which can detract from efficient assembly. Webcapsid [kap´sid] the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers. According to the number of subunits possessed by …
