常规说明ab94181 is a 293T cell transfected lysate in which Human Rsk 2 / MAPKAP Kinase 1b has been transiently over-expressed using a pCMV-Rsk 2 / MAPKAP Kinase 1b plasmid. The lysate is provided in 1 x Sample Buffer.
Note: For more details about how the transfected lysate was prepared view preparation notes
背景Function: Serine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB.
Tissue specificity: Expressed in many tissues, highest levels in skeletal muscle.
Disease: Defects in RPS6KA3 are the cause of Coffin-Lowry syndrome (CLS) [MIM:303600]; an X-linked dominant disorder characterized by severe mental retardation with facial and digital dysmorphisms, and progressive skeletal deformations.
Similarity: Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
Contains 1 AGC-kinase C-terminal domain.
Contains 2 protein kinase domains.
PTM: Autophosphorylated on Ser-386, as part of the activation process.
Ser-227 phosphorylation promotes Ser-386 phosphorylation and leads to basal activation. Full activation by growth factors requires additional phosphorylation on Ser-369.
