Product details:
Phosph-RSK1 p90 (S380) ELISA Kit (ab279914) is a very rapid, convenient, and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated RSK1 p90 protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.
This Sandwich ELISA kit is an
in vitro
enzyme-linked immunosorbent assay for the measurement of human phospho-RSK1 p90. An anti-pan RSK1 p90 antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and RSK1 p90 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and rabbit anti-phospho-RSK1 p90 (S380) antibody is used to detect phosphorylated RSK1 p90. After washing away unbound antibody, HRP conjugated anti-rabbit IgG is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of RSK1 p90 (S380) bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

RSK1 also known as p90 ribosomal S6 kinase 1 or p90RSK is a serine/threonine kinase with an approximate mass of 90 kDa. It belongs to the family of proteins that integrate signals from various extracellular stimuli. This kinase is expressed in diverse tissues including brain lung liver and skeletal muscle. At the molecular level RSK1 phosphorylates various target proteins that are involved in regulating cellular growth and survival. Its activity is regulated by phosphorylation events that occur at specific sites such as Serine 238 (E238 in some literature) which are critical for its function.
Biological function summary
RSK1 plays a fundamental role in cell proliferation and differentiation in the context of the p90 protein weight. It is an important component of the mitogen-activated protein kinase (MAPK) signaling pathway and forms part of multi-protein complexes that facilitate its activation and function. RSK1 influences various biological processes by phosphorylating transcription factors histone proteins and other kinases thereby regulating gene expression and protein synthesis. These actions highlight its influence in maintaining cellular homeostasis.
Pathways
RSK1 p90 interacts significantly with the MAPK/ERK and PI3K/AKT pathways. It acts downstream of ERK where it receives activating signals that enable it to phosphorylate substrates within the cell. This role supports its interaction with proteins like Akt and mTOR which are critical mediators of cell growth signals. The interplay between these pathways enables cells to respond to growth factors and stress contributing to the regulation of development and metabolism.
RSK1 is implicated in the progression of cancer and neurological disorders. In cancer abnormal RSK1 signaling can lead to unchecked cell growth and survival where it often interfaces with proteins such as C-RAF and BCL-2 to promote oncogenic pathways. In neurological disorders RSK1 influences pathways that regulate neuron survival and plasticity connecting it to proteins like CREB. Understanding RSK1's role in these conditions can provide insight into targeted therapies that may mitigate these diseases.
