Nucleocapsid Protein (N-protein)

Nucleocapsid Protein (N-protein)

Coronaviruses are enveloped viruses with a positive-sense RNA genome and with a nucleocapsid of helical symmetry.

Description
Coronaviruses are enveloped viruses with a positive-sense RNA genome and with a nucleocapsid of helical symmetry. Coronavirus nucleocapsid protein (N-protein) is a structural protein that binds to the coronavirus RNA genome, thus creating a shell (or capsid) around the enclosed nucleic acid. The N-protein also interacts with the viral membrane protein during viral assembly, assists in RNA synthesis and folding, plays a role in virus budding, and affects host cell responses, including cell cycle and translation. The N-protein is required for coronavirus RNA synthesis, and has RNA chaperone activity that may be involved in template switch. The N-protein is a most abundant protein of coronavirus. Nucleocapsid protein is a highly immunogenic phosphoprotein also implicated in viral genome replication and in modulating cell signaling pathways. Because of the conservation of N protein sequence and its strong immunogenicity, the N protein of coronavirus is chosen as a diagnostic tool. The array of diverse functional activities accommodated in the N protein goes far beyond to be a static structural protein and makes it an interesting target in the development of antiviral therapeutics.

ApoA1

ApoA1 (Apolipoprotein  A1) is synthesized in the liver and small intestine, and is the major protein component of high density lipoprotein (HDL) in the plasma. ApoA1 has a unique ability to capture and solubilize free cholesterol, and promotes cholesterol efflux from tissues to the liver for excretion. The process, called reverse cholesterol transport, is thought to inhibit atherogenesis.

Recombinant Human BDNF

Human Brain-Derived Neurotrophic Factor (BDNF) is a member of the Nerve growth factor family. BDNF is induced by cortical neurons, and is necessary for survival of striatal neurons in the brain. During development, BDNF promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems.

Streptavidin

Streptavidin is a non-glycosylated, 52.8 kDa, tetrameric bacterial protein isolated from Streptomyces avidinii with a very high affinity for biotin. Streptavidin-biotin bond is the strongest known non-covalent interaction with Kd ~10-15 M. Because streptavidin lacks any carbohydrate modification and has a near-neutral pI, it has the advantage of much lower nonspecific binding than avidin.

BirA Biotin-protein Ligase

Biotin-protein ligase (EC 6.3.4.15) activates biotin to form biotinyl 5' adenylate and transfers the biotin to biotin-accepting proteins. It also functions as a biotin operon repressor.
