The infectious laryngotracheitis virus (ILTV) gene encoding a homologue to the ICP4 protein of herpes simplex virus (HSV) has been mapped to the inverted repeat region. The complete nucleotide sequence of ILTV ICP4 has been determined. The ILTV ORF encoding ICP4 is 4386 nucleotides long, calculated from the first of four ATG codons, and has an overall G+C(More)
A 4.8 kilobase segment located at the left-terminal in the unique long (UL) region of infectious laryngotracheitis virus (ILTV) SA-2 strain contained three open reading frames (ORFs). The first of 421 amino acids (aa) was located at map units 0.065 to 0.07, and its predicted 48 kiloDaltons (kDa) protein product has significant homology to the immediate(More)
An infectious laryngotracheitis virus (ILTV, gallid herpesvirus 1) gene homologous to glycoprotein D of herpes simplex virus (HSV) was identified and characterized by its nucleotide and derived amino acid sequence. The ILTV gD gene is located in the unique short region (U(s)) and contains an open reading frame capable of specifying a polypeptide of 380(More)
Clones representing 90% of the genome of Gallid herpesvirus 1 (infectious laryngotracheitis virus; ILTV) were obtained and used in hybridization experiments to construct EcoRI, KpnI amd SmaI physical maps. The genome was 155 kilobase pairs (kbp) and comprised of a long unique sequence (120 kbp) and a short unique sequence (17 kbp) bounded by repeat(More)
The nucleotide sequence of 10.6 kilobase pairs (kbp) at the leftterminus of infectious laryngotracheitis virus (ILTV) SA-2 vaccine strain was determined. Several features were elucidated, including, 102 base pair (bp) inverted repeats separated by 750 bp of unique sequence which contains an NF-1 binding site indicating that the terminal may be a site for an(More)
To localize the gene encoding the 60 kD glycoprotein (gp60) of infectious laryngotracheitis virus (ILTV), a library of the ILTV genome was constructed in the lambda gt11 expression vector. Twelve recombinant bacteriophages expressing gp60 epitopes as fusion products with beta-galactosidase were detected by immunoscreening with monoclonal antibodies specific(More)
The nucleotide sequence of an infectious laryngotracheitis virus (ILTV) gene which maps immediately upstream from the glycoprotein 60 (gp60) gene was determined. The gene, designated p32, encodes a predicted polypeptide of 298 amino acids with an estimated M(r) of 32,000 daltons. The predicted protein sequence has four potential N-glycosylation sites and a(More)
The polypeptides associated with infection of primary chicken kidney (CK) cells with infectious laryngotracheitis virus (ILTV) were examined by metabolic labelling with [35S]methionine and SDS-PAGE. Polypeptide synthesis was followed over the first 24 h post-infection (p.i.) as this was shown to be the period of viable virus production. A total of 16 ILTV(More)
The DNA sequence of 4005 nucleotides from the Kpnl O and part of Kpnl K fragments in the short unique region of infectious laryngotracheitis virus (ILTV) was determined. The sequence contained two complete and one partial open reading frames (ORFs). The partial ORF was open at the 5' end of the sequence and represented the NH2-terminal 118 amino acids (aa)(More)
The nucleotide sequence of the infectious laryngotracheitis virus (ILTV) gene encoding the 205K complex glycoprotein (gp205) was determined. The gene is contained within a 3-kb EcoRI restriction fragment mapping at approximately map coordinates 0.23 to 0.25 in the UL region of the ILTV genome and is transcribed from right to left.
