RICTOR Protein is a protein. This page describes its structure, normal nervous system function, role in neurodegenerative disease, and potential as a therapeutic target. [@zhou2021]

RICTOR (Rapamycin-Insensitive Companion of mTOR) is an essential and unique component of the mechanistic Target of Rapamycin Complex 2 (mTORC2). Unlike its related complex mTORC1, which contains RAPTOR, RICTOR defines mTORC2 and is critical for its function in regulating neuronal survival, synaptic plasticity, cytoskeletal dynamics, and cellular stress responses. In the context of neurodegenerative diseases, RICTOR and mTORC2 signaling are increasingly recognized for their essential roles in maintaining neuronal health, and their dysregulation contributes to pathology in Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and multiple sclerosis (MS) [1](https://pubmed.ncbi.nlm.nih.gov/19279218/). [@yang2022]

Molecular Architecture and Biochemistry

RICTOR Structure and Domain Organization

RICTOR is a large protein of approximately 200 kDa (1,721 amino acids in humans), encoded by the RICTOR gene located on chromosome 5p13.1. The protein contains several structural domains that mediate its functions: [@liu2020]

RICTOR as a Scaffold Protein

RICTOR lacks catalytic activity but performs several essential functions: [@wang2019]

mTORC2 Complex Composition

mTORC2 is one of two structurally and functionally distinct mTOR complexes. The complete composition includes: [@park2021]

• mTOR (mechanistic Target of Rapamycin): The catalytic subunit with protein kinase activity
• RICTOR: Unique to mTORC2, required for complex integrity
• mLST8 (mammalian Lethal with Sec13 protein 8): Provides stability, also known as GβL

Signaling Pathways and Substrates

AKT/PKB Activation

One of the best-characterized functions of mTORC2 is the phosphorylation of AKT/PKB at Ser473 [2](https://pubmed.ncbi.nlm.nih.gov/22728832/). This phosphorylation is critical for:
