Mumps virus small hydrophobic protein targets ataxin-1 ubiquitin-like interacting protein (ubiquilin 4).
The small hydrophobic (SH) protein of mumps virus has been reported to interfere with innate immunity by inhibiting tumour necrosis factor alpha-mediated apoptosis. In a yeast two-hybrid screen we have identified the ataxin-1 ubiquitin-like interacting protein (A1Up) as a cellular target of the SH protein. A1Up contains an amino-terminal ubiquitin-like (UbL) domain, a carboxy-terminal ubiquitin...
متن کاملIdentification and characterization of an ataxin-1-interacting protein: A1Up, a ubiquitin-like nuclear protein.
Expansion of a polyglutamine tract within ataxin-1 causes spinocerebellar ataxia type 1 (SCA1). In this study, we used the yeast two-hybrid system to identify an ataxin-1-interacting protein, A1Up. A1Up localized to the nucleus and cytoplasm of transfected COS-1 cells. In the nucleus, A1Up co-localized with mutant ataxin-1, further demonstrating that A1Up interacts with ataxin-1. Expression ana...
متن کاملThe Ubiquitin-Like Protein PLIC-1 or Ubiquilin 1 Inhibits TLR3-Trif Signaling
BACKGROUND The innate immune responses to virus infection are initiated by either Toll-like receptors (TLR3/7/8/9) or cytoplasmic double-stranded RNA (dsRNA)-recognizing RNA helicases RIG-I and MDA5. To avoid causing injury to the host, these signaling pathways must be switched off in time by negative regulators. METHODOLOGY/PRINCIPAL FINDINGS Through yeast-two hybrid screening, we found that...
متن کاملmRNA sequence and deduced amino acid sequence of the mumps virus small hydrophobic protein gene.
The mRNA of a putative small hydrophobic protein (SH) of mumps virus was identified in mumps virus-infected Vero cells, and its complete nucleotide sequence was determined by sequencing the genomic RNA and cDNA clones and partial sequencing of mRNA. The SH mRNA is 310 nucleotides long excluding the poly(A) and contains a single open reading frame encoding a protein of 57 amino acids with a calc...
متن کاملCharacterization of three co-circulating genotypes of the small hydrophobic protein gene of mumps virus.
Eighteen virus isolates and 22 serum samples collected between 1971 and 1997 from patients with mumps were genotyped by PCR with specific primer pairs for the A, C and D genotypes of the small hydrophobic (SH) protein gene. All serum samples were subjected to nucleotide sequence analysis of the gene, and the deduced 57-amino-acid sequences were aligned with previously published sequences from t...
