Anti-Rsk1 antibody produced in rabbit

Ribosomal S6 kinase 1(Rsk1) is a ubiquitously expressed, mitogen-activated protein that belongs to the serine/threonine protein kinases family. Several isoforms of Rsk have been cloned from mouse (Mo1 and Mo2) 4, 5 and human (HU1-3) source. All of these isoforms encode proteins with calculated molecular masses of about 70 kDa. Their apparent higher masses (90 kDa) may be due to hyperphosphorylation after activation.

Synthetic peptide corresponding to amino acids 707-723 of human Rsk1 coupled to KLH.

Anti-Rsk1 antibody can be used in microarray and western blotting.

Rsk1 has a pivotal role in facilitating MEK-MAP kinase cell survival signaling and supressing pro-apoptotic function of BAD by phosphorylating . Anti-Rsk1 antibody can be used for studying differential tissue expression of (p90rsk) and its intracellular localization in normal and neoplastic tissues. It can also be used to detect (p90rsk).

Ribosomal S6 kinase 1(Rsk1) is regulated via separate signal transduction pathways in response to mitogenic stimulation. It is an important component in nuclear signaling processes. Activation of p90rsk occurs rapidly through phosphorylation of Thr396 located in the kinase catalytic domain. Rsk can phosphorylate and regulate the activity of other molecules such as transcription factor c-fos.
