Phosphorylated Proline-Rich AKT1 Substrate 1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** A post-translationally modified form of proline-rich AKT1 substrate 1 protein (AKT1S1) where one or more of the serine or threonine residues are phosphorylated. Increased phosphorylation of AKT1S1 can be correlated with increased cell proliferation and tumor progression.

**Synonyms:** - Phospho-PRAS40 - Phospho-Proline-Rich AKT1 Substrate 1 - Phospho-pAKT1S1 - p-PRAS40 - pAKT1S1 - pPRAS40
