What is p44 42 MAPK?

What is p44 42 MAPK?

p44/42 MAPK (Erk1/2) Antibody detects endogenous levels of total p44/42 MAP kinase (Erk1/Erk2) protein. In some cell types, this antibody recognizes p44 MAPK more readily than p42 MAPK. The antibody does not recognize either JNK/SAPK or p38 MAP kinase.

What is P ERK1 2?

Extracellular signal-related kinase (ERK1/2 or p42/44) is a kinase in the mitogen-activated protein kinase (MAPK) family and phosphorylation of ERK (p-ERK) can be used as a common end point measurement for the activation of many classes of G protein coupled receptors (GPCR).

What does ERK1 stand for?

The extracellular signal-regulated kinase 1/2 (ERK1/2) cascade is a central signaling pathway that regulates a wide variety of stimulated cellular processes, including mainly proliferation, differentiation, and survival, but apoptosis and stress response as well.

Is AKT a protein?

Akt is a serine/threonine-specific protein kinase that plays a critical role in controlling the balance between survival and death pathways in cells. The Akt kinase family comprises three highly homologous isoforms: Akt1 (PKBα), Akt2 (PKBβ), and Akt3 (PKBγ) [4,14].

What does ERK P do?

Key components of the MAPK/ERK pathway. “P” represents phosphate, which communicates the signal. Further downstream, phosphate signal activates MAPK (also known as ERK). Bottom, signal enters the cell nucleus and causes transcription of DNA, which is then expressed as protein.

Is Ras a MAPK?

The Ras/Raf/MAPK pathway is probably the best characterized signal transduction pathway in cell biology. The function of this pathway is to transduce signals from the extracellular milieu to the cell nucleus where specific genes are activated for cell growth, division and differentiation.

What does Akt protein stand for?

Ak strain transforming
The name Akt stands for Ak strain transforming. The origins of the Akt name date back to 1928, where J. Furth performed experimental studies on mice that developed spontaneous thymic lymphomas. Mice from three different stocks were studied, and the stocks were designated A, R, and S.

How do you activate Akt protein?

Akt activation Thus PI3K activity is essential for translocation of Akt to the membrane. Interaction with PI(3,4,5)P3 causes conformational changes and exposure of phosphorylation sites Thr308 in the kinase domain and Ser473 in the C-terminal domain. Akt is partially activated by phosphorylation of T308 by PDK1.

How are ERK1 and ERK2 MAP kinases related?

ERK1/2 MAP kinases: structure, function, and regulation ERK1 and ERK2 are related protein-serine/threonine kinases that participate in the Ras-Raf-MEK-ERK signal transduction cascade.

Which is a docking site of ERK1 / 2?

Besides this primary structure requirement, many ERK1/2 substrates possess a D-docking site, an F-docking site, or both. A variety of scaffold proteins including KSR1/2, IQGAP1, MP1, β-Arrestin1/2 participate in the regulation of the ERK1/2 MAP kinase cascade.

How is the dephosphorylation of ERK1 / 2 regulated?

The regulatory dephosphorylation of ERK1/2 is mediated by protein-tyrosine specific phosphatases, protein-serine/threonine phosphatases, and dual specificity phosphatases. The combination of kinases and phosphatases make the overall process reversible.
