Detection of Human PRAS40 by Western Blot. Western blot shows lysates of 293T human embryonic kidney cell line, A549 human lung carcinoma cell line, MDA-MB-468 human breast cancer cell line, and T47D human breast cancer cell line. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human PRAS40 Monoclonal Antibody (Catalog # MAB6408) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PRAS40 at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human PRAS40 by Simple WesternTM. Simple Western lane view shows lysates of 293T human embryonic kidney cell line, loaded at 0.5 mg/mL. A specific band was detected for PRAS40 at approximately 65 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human PRAS40 Monoclonal Antibody (Catalog # MAB6408). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
PRAS40 in HeLa Human Cell Line. PRAS40 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human PRAS40 Monoclonal Antibody (Catalog # MAB6408) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

PRAS40 (Proline-rich AKT1 substrate 1; also Akt1S1 and p39) is a 40-42 kDa cytoplasmic phosphoprotein that lacks generally recognized structural motifs. It is widely expressed and is considered to be key regulator of mTORC1 (mTOR plus raptor and G beta L), a complex through which Akt signals into the cell. Through phosphorylation, mTORC1 activity is upregulated by PRAS40. In particular, nonphosphorylated PRAS40 binds to and serves as a negative regulator of mTORC1 activity. Upon Insulin signaling, PRAS40 is phosphorylated on Thr246, Ser221 and Ser183. This causes it to bind 14-3-3 and results in its dissociation from mTORC1, freeing up mTOR to regulate (positively or negatively) protein synthesis. Human PRAS40 is 256 amino acids (aa) in length. It contains one extended Pro-rich region (aa 35-96) plus at least nine utilized Ser/Thr phosphorylation sites. There is one alternative start site at Met131. Over aa 119-256, human PRAS40 shares 93% aa identity with mouse PRAS40.
