RSK1 (10B1) Antibody

p90-RSK1 (90 kDa ribosomal protein S6 kinase 1) is a serine/threonine kinase that plays a role in mediating the growth-factor and stress induced activation of the transcription factor CREB. p90-RSK1 forms a complex with either ERK1 or ERK2 in quiescent cells and transiently dissociates following mitogenic stimulation.
