Background Information

RPS6KA3(Ribosomal protein S6 kinase alpha-3) is also named as ISPK1, MAPKAPK1B, RSK2 and belongs to the protein kinase superfamily. It localizes at the kinetochores under spindle checkpoint conditions, and during mitosis, associated with the centrosomes, the spindle and at the mid-body(PMID:20383198). It is required for EGF activated phosphorylation of histone H3, which may cause chromatin remodeling and facilitate gene transcription and maybe playing an essential regulatory role in protein synthesis during cell proliferation.
