MERS Nucleocapsid protein, His Tag

Nucleocapsid (N) protein is the most abundant protein found in coronavirus. CoV N protein is a highly immunogenic phosphoprotein important for viral genome replication and modulation of cell signaling pathways. It was first identified by a research team while they were screening for ADP-ribosylated proteins during coronavirus (CoV) infection (Grunewald M. E., et al. 2017, Virology; 517: 62-68) . The array of diverse functional activities accommodated in N protein makes it more than a structural protein but also an interesting target in the development of antiviral therapeutics. Because of the conservation of N protein sequence and its strong immunogenicity, N protein of coronavirus is chosen as a diagnostic tool.

Product Specifications

Background

Specifications

This protein carries a polyhistidine tag at the C-terminus. This protein contains a furin cleavage site, 251-RHKR-254, and is partially processed into N and C-terminal fragment with calculated MW of 17.1 kDa and 19.7 kDa respectively. The protein migrates as 23-25 kDa (C-terminus) and 46-73 kDa (full length) under reducing (R) condition (SDS-PAGE) due to glycosylation.
