Description : (at3g08720 : 90.9) Encodes a ribosomal-protein S6 kinase. Gene expression is induced by cold and salt (NaCl). Activation of AtS6k is regulated by 1-naphthylacetic acid and kinetin, at least in part, via a lipid kinase-dependent pathway. Phosphorylates specifically mammalian and plant S6 at 25 degrees C but not at 37 degrees C. Involved in translational up-regulation of ribosomal proteins.; Arabidopsis thaliana protein kinase 19 (ATPK19); CONTAINS InterPro DOMAIN/s: Protein kinase, ATP binding site (InterPro:IPR017441), Serine/threonine-protein kinase domain (InterPro:IPR002290), Serine/threonine-protein kinase-like domain (InterPro:IPR017442), AGC-kinase, C-terminal (InterPro:IPR000961), Protein kinase-like domain (InterPro:IPR011009), Protein kinase, C-terminal (InterPro:IPR017892), Serine/threonine-protein kinase, active site (InterPro:IPR008271), Protein kinase, catalytic domain (InterPro:IPR000719), Tyrosine-protein kinase, catalytic domain (InterPro:IPR020635); BEST Arabidopsis thaliana protein match is: protein-serine kinase 1 (TAIR:AT3G08730.1); Has 133901 Blast hits to 131707 proteins in 4554 species: Archae - 204; Bacteria - 15943; Metazoa - 48718; Fungi - 13429; Plants - 32816; Viruses - 561; Other Eukaryotes - 22230 (source: NCBI BLink). & (reliability: 181.8) & (original description: no original description)
