Summary
This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS).

tat Interaction of HIV-1 Tat with p90 ribosomal S6 kinase 2 (RSK2) is observed in vivo and in vitro. The critical interacting residues lie within amino acids 36-39 in Tat and 1-360 in RSK2. RSK2 supports HIV-1 Tat transactivation via binding to F38 PubMed
tat Activation of the N-terminal RSK2 kinase activity is enhanced by HIV-1 Tat in a dose-dependent manner. PubMed
tat Phosphorylation of serine 227 in RSK2 is increased by Tat; mutation at position F38 abolishes the Tat-mediated phosphorylation of RSK2. PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
