Anti-p52 S6 kinase

catalytic activity:ATP + a protein = ADP + a phosphoprotein.,caution:Instead of Lys-820, Arg-820 is found at the binding site.,domain:The first protein kinase domain appears to be a pseudokinase domain as it does not contain the classical characteristics, such as the ATP-binding motif, ATP-binding site and active site.,function:May be involved in transmitting sphingosine-1 phosphate (SPP)-mediated signaling into the cell.,similarity:Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. S6 kinase subfamily.,similarity:Contains 1 MIT domain.,similarity:Contains 1 PX (phox homology) domain.,similarity:Contains 2 protein kinase domains.,subcellular location:Also found in some small dot-like or ring-shaped early endosome structures.,subunit:Interacts with SPHK1 and phosphatidylinositol 3-phosphate.,tissue specificity:Highly expressed in testis, skeletal muscle, brain, heart, placenta, kidney and liver and weakly expressed in thymus, small intestine, lung and colon., Protein function: May be involved in transmitting sphingosine-1 phosphate (SPP)-mediated signaling into the cell (PubMed:12077123). Plays a role in the recruitment of PRDX3 to early endosomes (PubMed:15750338). [The UniProt Consortium] Recommended dilutions: Western Blot: 1/500 - 1/2000. Immunofluorescence: 1/200 - 1/1000. ELISA: 1/20000. Not yet tested in other applications.. Cellular localization: Cytoplasm . Membrane . Early endosome .
