mSIRK

2 Cited Publications

Avis client

Based on 2 publication(s) in Google Scholar

mSIRK (G-Protein βγ Binding Peptide) is an cell-permeable activator of ERK1/2, with EC₅₀ of 2.5-5 μM. mSIRK disrupts the interaction between α and βγ subunits and promotes α subunit dissociation without stimulating nucleotide exchange.

In Vitro

mSIRK (1.2-30 μM, 1-30 min) can rapidly activate extracellular signal-regulated kinases 1/2, stimulates the phosphorylation of Jun N-terminal kinase, the phosphorylation of p38 mitogen-activated protein kinase and the activity of phospholipase C, and leads to the internal storage and release of Ca²⁺^[1].
mSIRK (10 μM, 24 h) rescues the inhibitory effect on cell proliferation and migration induced by Y27632 (HY-10071)^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[1]

Cell Line:

RASM, ddtMF2, MDA, Rat2, HEK293, COS7
Concentration:

1.2, 2.5, 5, 10, 30 μM
Incubation Time:

1, 2, 5, 10, 15, 30 min
Result:

Led to rapid and dose-dependent activation of ERK1/2.
Reached full activation after 1 minute of application and weakens within 30 minutes.
The phosphorylation of p38 MAP kinase and Jun kinase increased.
The activation degree of ERK1/2 depends on the cell type.

Cell Viability Assay^[2]

Cell Line:

SCC9 cell
Concentration:

10 μM
Incubation Time:

24 h
Result:

Partially rescued the inhibitory effect on cell proliferation and migration induced by Y27632.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
