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'. Plays an essential role in embryonic growth and development. Ref.1 Ref.7 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 PRR5 within the TORC2 complex. May interact with PRR5L. Ref.1 Ref.7 Ref.10 Ref.11 |
| Post-translational modification | Phosphorylated by MTOR; when part of mTORC2. Phosphorylated at Thr-1135 by RPS6KB1; phosphorylation of RICTOR inhibits mTORC2 and AKT1 signaling. Ref.7 Ref.16 |
| Sequence similarities | Belongs to the pianissimo family. |
| Sequence caution | The sequence CAH18135.1 differs from that shown. Reason: Wrong choice of CDS. |

Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 Ref.1 (identifier: Q6R327-1) 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 Ref.17 (identifier: Q6R327-4) The sequence of this isoform differs from the canonical sequence as follows: 252-257: RILAPY → NFSTLY 258-1708: Missing. | ||||||
| Note: No experimental confirmation available. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 3 Ref.17 (identifier: Q6R327-3) The sequence of this isoform differs from the canonical sequence as follows: 1379-1379: R → RIDFKKKHVGGIRSLRPTITNNLFR | ||||||
| Note: No experimental confirmation available. |
