Ribosomal protein S6 kinase, 70kDa, polypeptide 1 (RPS6KB1) undergoes acetylation, phosphorylation, and ubiquitination. It is involved in a variety of functions including glucose homeostasis, cell survival, and proliferation. RPS6KB1 also participates in cell structure and organization. It is implicated in ovarian cancer progression, muscle hypertrophy, aging, immunity, and memory. RPS6KB1 also regulates the replication and transcription of mumps virus (MuV).
