International audience. The nucleoprotein (N) from SARS-CoV-2 is an essential cofactor of the viral replication transcription complex and as such represents an important target for viral inhibition. It has also been shown to colocalize to the transcriptase-replicase complex, where many copies of N decorate the viral genome, thereby protecting it from the host immune system. N has also been shown to phase separate upon interaction with viral RNA. N is a 419 amino acid multidomain protein, comprising two folded, RNA-binding and dimerization domains spanning residues 45$-$175 and 264$-$365 respectively. The remaining 164 amino acids are predicted to be intrinsically disordered, but there is currently no atomic resolution information describing their behaviour. Here we assign the backbone resonances of the first two intrinsically disordered domains (N1, spanning residues 1$-$44 and N3, spanning residues 176$-$263). Our assignment provides the basis for the identification of inhibitors and functional and interaction studies of this essential protein.
