RPS6KB1 phosphorylates IRS1 on S639. 8 / 8

reach
"mTOR and its downstream effector S6K1 suppress IRS1 activity by directly phosphorylating IRS1 at Ser636 and Ser639 and Ser307, respectively, which leads to desensitization of insulin signaling."

"In addition, when mTORC1 is activated, S6K1 could directly phosphorylate Insulin receptor substrate 1 (IRS1; S307 and S636 and S639) and promote its degradation, which subsequently blunts phosphoinositide 3-kinase (PI3K)-AKT activation and its downstream effects such as glucose uptake and glycogen accumulation."

"Nevertheless, s6k1-deficient mice remain sensitive to insulin owing to the apparent loss of a negative feedback loop from s6k1 to insulin receptor substrate 1 (irs1), which blunts s307 and s636/s639 phosphorylation; thus under conditions of nutrient satiation s6k1 negatively regulatesinsulin."

"In this report, we identified insulin receptor substrate 1 (IRS-1), a critical mediator of the insulin/insulin-like growth factor 1 signaling, as a proteolytic target of the CUL7 E3 ligase in a manner that depends on mammalian target of rapamycin and the p70 S6 kinase activities.Elimination of phosphorylation at S307/S312/S527/S636/S639 renders V5-IRS-1 partially resistant to degradation by Fbw8"
