For example, in the PTP motif 1 (NXXKNRY), known as a phosphotyrosine recognition loop that restricts the substrate specificity to tyrosine-phosphorylated peptide, HD-PTP (YSLKNRH) displays divergences that are also observed in the two inactive receptor-like PTPs IA2 and IA2β [1].
Based on our finding that the E1B55k-deficient adenovirus was able to replicate in human primary hepatocytes, we therefore designed an adenovirus carrying E1A and attenuated E1B gene driven by the α-fetoprotein promoter (Adv-AFP-E1AdB), thus restricting the replication specificity in AFP-producing HCC.
Ribosome occupancy of AAC/U, CAC/U, or GAC/U codons was not altered in ncs2Δ yeast, suggesting that U34 2-thiolation does not restrict the decoding specificity of tEUUC, tKUUU, and tQUUG.
This specificity restricts the virus to a very limited type of cell.
However, these strategies are restricted by the specificity and availability of kinase antibodies or substrates.
For example, although suicidal intent certainly seems relevant, 7 available instruments show inconsistent results concerning the relation between suicidal intent and future suicide; furthermore, low specificity of predictive factors restricts the precision of predictions.
This splicing event establishes a selectivity filter to restrict the ligand binding specificity of FGFRb and FGFRc isoforms to mesenchymally and epithelially derived fibroblast growth factors (FGFs), respectively [ 5].
Accordingly, the NS2B/NS3Pro part restricts substrate specificity of the C-terminal NS3Hel domain, however, in the absence of NS2B, the NS3 protein might dissociate from membranes and interfere with host DNA after translocation into the host-cell nucleus (Chernov et al., 2008).
Conventional biomarkers of pancreatitis such as CA19-9 and carcinoembryonic antigen may also be elevated in benign conditions or in cancers; hence their inadequate sensitivity and specificity restricted the use of those markers in the early diagnosis of pancreatitis [ 12– 12].
