RSK1 [p Ser380] Antibody Summary

• Immunogen: Synthetic phosphopeptide derived from a region of human RSK1 that contains serine 380.
• Modification: p Ser380
• Specificity: Cross-reaction with RSK2 (85% homologous) is expected based on peptide competition by the analogous sequence from RSK2. Cross-reaction with RSK3 (77% homologous) and RSK4 (85% homologous) is possible but has not been tested.
• Predicted Species: Rat (100%). Backed by our 100% Guarantee.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: RPS6KA1
• Purity: Immunogen affinity purified

Applications/Dilutions

• Dilutions:
  • Western Blot 1:1000
• Application Notes: WB: Use at a dilution of 1/1000. Detects a band of approximately 88 kDa.

Reactivity Notes

Cross-reacts with Human and Mouse.Expected to cross-react with Rat (100% identity with immunogen) due to sequence homology. Not yet tested in other species.

Background

RSK1 (also called MAPK Activated Protein Kinase-1a; MAPKAP-K1a) is a member of the broadly expressed p90 Ribosomal S6 Kinase (RSK) family of serine/threonine kinases that also includes RSK2 (MAPKAP-K1b), RSK3 (MAPKAP-K1c), and RSK4. RSK proteins are substrates for and downstream transducers of MAPK signaling proteins, primarily ERK1&2. RSK proteins possess two separate kinase domains, the C-terminal kinase domain and the N-terminal kinase domain, separated by a linker region containing a hydrophobic motif. Activation of RSK1 is a multi-step process involving phosphorylation of multiple residues within the three domains, changes in RSK protein localization, and modulation of RSK complex formation with ERK1&2 and/or 14-3-3 beta proteins. RSK is activated by many stimuli including growth factors, phorbol esters, cAMP, heat shock, and irradiation. ERK 1&2 phosphorylates threonine 573 of the C-terminal kinase domain, thereby stimulating this kinase activity and leading to phosphorylation of serine 380 within the linker region. Phosphoserine 380 is part of a docking site for PDK1, a constitutively active cytoplasmic kinase that phosphorylates serine 221 and thereby activates the N-terminal kinase domain to phosphorylate various substrates that include transporters, transcription factors, and transcription co-activators.
