Sentence examples for binding perk from inspiring English sources

As a consequence, without BiP binding, PERK and IRE-1 α autooligomerize and undergo autophosphorylation, leading to the activation of downstream signaling.

To test whether IPA binds PERK at its ATP binding site, we purified the cytosolic domain of PERK as a GST-PERK fusion protein.

Assuming a Kd of 2.8 μM for IPA-binding to PERK as determined by PERK inhibition, we estimate that approximately 15% of the PERK molecules are occupied by IPA under assay conditions that yield maximal activation.

First, CN binding to PERK enhances inhibition of protein translation to allow the cell time to recover.

In ChiP-Seq data sets, there is no AR binding to PERK or eIF2α genes and thus the effects could be mediated by interaction of AR with other signaling pathways (for a review, see Kaarbo et al, 2007).

The authors propose that at low (non-saturating) concentrations of IPA, IPA binding to one PERK protomer promotes dimerization and transactivation of a second PERK protomer bound to ATP, resulting in auto-phosphorylation of PERK and subsequent phosphorylation of eIF2α.

We propose that IPA binding biases the PERK kinase towards its active conformation, which trans-activates apo-PERK molecules.

Combining library selection and knowledge-based design, we created an ERK activity biosensor by derivatizing a DARPin specific for phosphorylated ERK with a solvatochromatic merocyanine dye, whose fluorescence increases upon pERK binding.

α-Solanine treatment caused an increase in the expression of endoplasmic reticulum (ER) stress proteins (BiP, activating transcription factor 6 (ATF6), X-box-binding protein 1, PERK, inositol-requiring transmembrane kinase/endonuclease 1, ATF4 and CCAAT-enhancer-binding protein (C/EBP -homologous protein) suggesting aC/EBP -homologouslded protein resuggestinghwactivation

PERK activation by IPA could be due to direct binding of IPA to PERK, or it could be caused by indirect activation of PERK by IRE1.

There are quite straightforward biochemical experiments that could deliver such evidence: i) Given that IPA strongly stabilizes the active conformation of IRE1, one would expect quite strong cooperative binding of IPA to PERK if the proposed model is correct: Binding of IPA to PERK causes the neighboring apo-PERK molecules to be in the active state, hence the high affinity state.
