• Species Reactivity

  Human

• Specificity

  Detects human MSK1 and MSK2 when phosphorylated at S376 and S360, respectively. The amino acid sequence surrounding S360 of mouse MSK2 is identical to the phosphopeptide antigen.

Background: MSK1/MSK2

Mitogen- and stress-activated protein kinase 1 (MSK1), also known as ribosomal protein S6 kinase 5 (RPS6KA5), belongs to the AGC family of kinases. Both MSK1 and the related MSK2, also known as RSKB and RPS6KA4, have two kinase domains connected by a regulatory linker region, and are activated by the mitogen-activated protein kinases ERK1, ERK2, and p38. Nuclear MSK phosphorylates and activates a number of transcription factors, including ATF1 and CREB.

• Long Name:

  Mitogen- and Stress-activated Protein Kinase 1 and 2

• Alternate Names:
