title: In silico identification of a putative new paramyxovirus related to the Henipavirus genus.
abstract: A database search for genes encoding paramyxoviral proteins revealed sequences that were designated as human but presented strong evidence of being of viral origin. The two cDNA-derived sequences designated AngRem104 and AngRem52 were originally described as human gene products that were upregulated by angiotensin II in primary mesangial kidney cells. However, their high degree of sequence relatedness to known viral proteins suggests that they represent the P/C/V, M, and F genes of a putative new member of family Paramyxoviridae. Comparison of deduced amino acid sequences and nucleotide motifs suggests that this putative virus is a divergent relative of the Hendra and Nipah viruses; hence, we suggest henipa-like virus or HNLV as a provisional name. Compared to Nipah virus, the percentage of identical (similar) amino acids varied from 19% (42%) for the C protein to 51% (75%) for the M protein. The presence and conservation of presumptive viral transcription start and stop signals and an apparent P editing motif also indicate a relationship of this putative virus to the henipaviruses. Given the highly pathogenic nature of the henipaviruses, the origin of these sequences is enigmatic, and attempts to identify and isolate HNLV are warranted.
