该基因编码丝氨酸/苏氨酸激酶rsk（核糖体s6激酶）家族的一个成员。该激酶包含一个激酶催化结构域并磷酸化s6核糖体蛋白和真核翻译起始因子4b（eif4b）。s6的磷酸化导致蛋白质合成和细胞增殖增加。[由RefSeq提供，2015年1月]
This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains a kinase catalytic domain and phosphorylates the S6 ribosomal protein and eukaryotic translation initiation factor 4B (eIF4B). Phosphorylation of S6 leads to an increase in protein synthesis and cell proliferation. [provided by RefSeq, Jan 2015]
