The roles of EPIYA sequence to perturb the cellular signaling pathways and cancer risk
Abstract It was shown that several pathogenic bacterial effector proteins contain the Glu-Pro-Ile-Tyr-Ala (EPIYA) or a similar sequence. These bacterial EPIYA effectors are delivered into host cell via type III or IV secretion system, where they undergo tyrosine phosphorylation at the EPIYA sequences, which triggers interaction with multiple host cell SH2 domain-containing proteins and thereby...
متن کاملPrevalence of cagA EPIYA motifs in Helicobacter pylori among dyspeptic patients in northeast Thailand.
The aims of this study were to determine the prevalence of cagA type in Helicobacter pylori isolated from dyspeptic patients in northeastern Thailand and to determine whether the pattern of cagA EPIYA motifs were associated with clinical outcomes. One hundred and forty-seven H. pylori-infected dyspeptic patients were enrolled, of whom 68 had non-ulcer dyspepsia (NUD), 57 peptic ulcer disease (P...
متن کاملPrevalence of EPIYA motifs in Helicobacter pylori strains isolated from patients with gastroduodenal disorders in northern Iran
Background: Cytotoxin-associated gene A (CagA)-positive strains of Helicobacter pylori are associated with gastroduodenal diseases. Evidences have suggested that the type of H pylori CagA EPIYA motifs may be associated with specific disorders (i.e., gastritis, peptic ulcer, or gastric cancer). We investigated the prevalence of different EPIYA motifs (A, B, C, or D) in H. pylori strains is...
متن کاملIdentifying Structural Motifs in Proteins
In biological macromolecules, structural patterns (motifs) are often repeated across different molecules. Detection of these common motifs in a new molecule can provide useful clues to the functional properties of such a molecule. We formulate the problem of identifying a given structural motif (pattern) in a target protein (example) and discuss the notion of complete matches vis-a-vis partial ...
متن کاملMammalian Hsp70 and Hsp110 proteins bind to RNA motifs involved in mRNA stability.
In this study, in vitro RNA binding by members of the mammalian 70-kDa heat shock protein (Hsp) family was examined. We show that Hsp/Hsc70 and Hsp110 proteins preferentially bound AU-rich RNA in vitro. Inhibition of RNA binding by ATP suggested the involvement of the N-terminal ATP-binding domain. By using deletion mutants of Hsp110 protein, a diverged Hsp70 family member, RNA binding was loca...
