General annotation (Comments)
| Function | Subunit of mTORC2, which regulates cell growth and survival in response to hormonal signals. mTORC2 is activated by growth factors, but, in contrast to mTORC1, seems to be nutrient-insensitive. mTORC2 seems to function upstream of Rho GTPases to regulate the actin cytoskeleton, probably by activating one or more Rho-type guanine nucleotide exchange factors. mTORC2 promotes the serum-induced formation of stress-fibers or F-actin. mTORC2 plays a critical role in AKT1 'Ser-473' phosphorylation, which may facilitate the phosphorylation of the activation loop of AKT1 on 'Thr-308' by PDK1 which is a prerequisite for full activation. mTORC2 regulates the phosphorylation of SGK1 at 'Ser-422'. mTORC2 also modulates the phosphorylation of PRKCA on 'Ser-657'. PRR5 plays an important role in regulation of PDGFRB expression and in modulation of platelet-derived growth factor signaling. May act as a tumor suppressor in breast cancer. Ref.6 Ref.8 |
| Subunit structure | Part of the mammalian target of rapamycin complex 2 (mTORC2) which contains MTOR, MLST8, PRR5, RICTOR, MAPKAP1 and DEPTOR. Contrary to mTORC1, mTORC2 does not bind to and is not sensitive to FKBP12-rapamycin. Binds directly to MTOR and RICTOR within the TORC2 complex. Ref.7 Ref.8 |
| Tissue specificity | Most abundant in kidney and liver. Also highly expressed in brain, spleen, testis and placenta. Overexpressed in several colorectal tumors. Ref.6 Ref.8 |
| Sequence similarities | Belongs to the PROTOR family. |

| Isoform 1 (identifier: P85299-1) Also known as: alpha; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: P85299-2) The sequence of this isoform differs from the canonical sequence as follows: 1-101: Missing. 102-107: KIRFYE → MAPMPT | ||||||
| Isoform 3 (identifier: P85299-3) Also known as: beta; The sequence of this isoform differs from the canonical sequence as follows: 1-9: Missing. | ||||||
| Note: Derived from EST data. No experimental confirmation available. | ||||||
| Isoform 4 (identifier: P85299-4) Also known as: gamma; The sequence of this isoform differs from the canonical sequence as follows: 1-95: Missing. | ||||||
| Note: Derived from EST data. No experimental confirmation available. | ||||||
| Isoform 5 (identifier: P85299-5) The sequence of this isoform differs from the canonical sequence as follows: 1-5: MRTLR → MVCLELSQREAWGSGSPEKMPAQPEGLY | ||||||
