Molecular cloning and characterization of the pseudorabies virus UL31 gene

M. L. Li, Zhao, Z. Y., Cui, W., Mo, C. C., Wang, J. L., and Cai, M. S., “Molecular cloning and characterization of the pseudorabies virus UL31 gene”, vol. 13, pp. 1832-1847, 2014.

We amplified a 816-bp sequence of the UL31 gene from the pseudorabies virus (PRV) Becker strain genome. Evidence that this was the UL31 gene was confirmed by cloning and sequencing. The PRV UL31 gene encodes a putative protein of 271-amino acid residues, which was designated the UL31 protein. Bioinformatic analysis indicated that PRV UL31 contains a conserved PHA03328 domain, closely related with the herpes virus nuclear egress lamina protein UL31 family and highly conserved among counterparts encoded by herpes UL31 genes.

Molecular cloning and characterization of the pseudorabies virus US1 gene

M. L. Li, Chen, J. H., Zhao, Z. Y., Zhang, K. J., Li, Z., Li, J., Mai, J. Y., Zhu, X. M., and Cai, M. S., “Molecular cloning and characterization of the pseudorabies virus US1 gene”, vol. 12, pp. 85-98, 2013.

Using polymerase chain reaction, a 1050-bp sequence of the US1 gene was amplified from the pseudorabies virus (PRV) Becker strain genome; identification of the US1 gene was confirmed by further cloning and sequencing. Bioinformatics analysis indicated that the PRV US1 gene encodes a putative polypeptide with 349 amino acids.

Molecular characterization of the pseudorabies virus UL2 gene

M. S. Cai, Wang, B. Y., Cui, W., Zhao, Z. Y., Chen, J. H., Wen, X. M., Li, Z., and Li, M. L., “Molecular characterization of the pseudorabies virus UL2 gene”, vol. 12, pp. 4147-4161, 2013.

A 948-bp sequence of the UL2 gene was amplified from the pseudorabies virus (PRV) Becker strain genome using polymerase chain reaction, and the gene identity was confirmed through further cloning and sequencing. Bioinformatic analysis indicated that the PRV UL2 gene encodes a putative polypeptide with 315-amino acid residues. Its encoding protein, designated UL2, has a conserved uracil-DNA glycosylase (UDG)_F1 domain, which is closely related to the herpesvirus UDG family and is highly conserved among its counterparts encoded by UDG genes.
