A ribosome is made up of two subunits, a small subunit, and a large subunit. These subunits come together before the translation of mRNA into a protein to provide a location for translation to be carried out and a polypeptide to be produced. [3] The choice of amino acid type to add is determined by a messenger RNA (mRNA) molecule. Each amino ...
Eukaryotic translation is the biological process by which messenger RNA is translated into proteins in eukaryotes. It consists of four phases: initiation, elongation, termination, and recapping. It consists of four phases: initiation, elongation, termination, and recapping.
It is the primary intracellular iron-storage protein in both prokaryotes and eukaryotes, keeping iron in a soluble and non-toxic form. In humans, it acts as a buffer against iron deficiency and iron overload. [3] Ferritin is found in most tissues as a cytosolic protein, but small amounts are secreted into the serum where it functions as an iron ...
A ribosomal protein (r-protein or rProtein [1] [2] [3]) is any of the proteins that, in conjunction with rRNA, make up the ribosomal subunits involved in the cellular process of translation. E. coli, other bacteria and Archaea have a 30S small subunit and a 50S large subunit, whereas humans and yeasts have a 40S small subunit and a 60S large ...
Protoglobin: a single domain globin found in archaea that is related to the N-terminal domain of globin-coupled sensors. [18] Truncated 2/2 globin: lack the first helix, giving them a 2-over-2 instead of the canonical 3-over-3 alpha-helical sandwich fold. Can be divided into three main groups (I, II and II) based on structural features.
Structure of rabbit eIF3 in the context of the 43S PIC, showing subunits a, c, e, f, h, k, l, and m. [1]Eukaryotic initiation factor 3 (eIF3) is a multiprotein complex that functions during the initiation phase of eukaryotic translation. [2]

Hemagglutinin is a class I fusion protein, [1] [2] having multifunctional activity as both an attachment factor and membrane fusion protein. Therefore, HA is responsible for binding influenza viruses to sialic acid on the surface of target cells, such as cells in the upper respiratory tract or erythrocytes , [ 3 ] resulting in the ...
