S71-p - RAC1 (human)
Orthologous residues
RAC1 (human): S71‑p, RAC1 iso2 (human): S71‑p, RAC1 (mouse): S71‑p, RAC1 (rat): S71‑p
Characterization
 Species studied:  no information
 Comments:  While this paper does not prove directly that this site is phosphorylated in vivo, it does present strong circumstantial evidence to support this argument. Additionally, CST has verified that it is phosphorylated in living cells (CST cat# 2461).
 Enzymes shown to modify site in vitro
Type Enzyme
KINASE Akt1 (human)
Downstream Regulation
 Effect of modification (function):  activity, inhibited
 Comments:  Phosphorylation of this site inhibits GTP binding activity of Rac1 without affecting its GTPase activity.
