Functional narrative |
Function: Encapsidates the genome protecting it from nucleases. The encapsidated genomic RNA is termed the nucleocapsid (NC) and serves as template for transcription and replication (By similarity).
SUBUNIT: Homomultimerizes to form the nucleocapsid. Binds to viral genomic RNA. N in nucleocapsid binds the P protein and thereby positions the polymerase on the template (By similarity).
Subcellular Location: Virion. Host cytoplasm (By similarity).
SIMILARITY: Belongs to the paramyxoviruses nucleocapsid family. -----------------------------------------------------------------------

| Comments:Habchi et al. (2010) found that "Henipah" virus N-tail contained four putative Molecular Recognition Features (MoRF): two alpha-MoRFs at aa 408-422 and 473-493, an irregular I-MoRF at aa 523-532, and a beta-MoRF at aa 444-464. However, based on the experimental CD in TFE studies and the Hydrophobic Cluster Analysis (HCA) plot, the predicted beta-MoRF is more likely an alpha-MoRF.
