Gene Snapshot

Repressed by TOR (REPTOR) encodes a transcription factor that shuttles between cytoplasm and nucleus depending on the state of the activity of the product of Tor. Together with its binding partner encoded by REPTOR-BP, it mediates much of the transcriptional response observed upon Tor complex 1 inhibition. [Date last reviewed: 2019-03-14]

Protein Signatures (InterPro)

Summaries

Gene Group (FlyBase)

BASIC LEUCINE ZIPPER TRANSCRIPTION FACTORS -: The basic leucine zipper (bZIP) transcription factors are sequence-specific DNA-binding proteins that regulate transcription. They are characterized by a 60-80 amino acid bZIP domain: a basic DNA binding domain followed by a leucine zipper dimerization domain. (Adapted from FBrf0152056).

Protein Function (UniProtKB)

Transcriptional regulator that acts in the TORC1 signaling pathway to regulate energy homeostasis and promote survival during nutrient deprivation. Interacts with REPTOR to form a transcriptional activator complex that functions downstream of TORC1 to up-regulate the expression of most target genes induced by TORC1 inhibition. In the complex, acts as the transcriptional activator. Under normal conditions TORC1 is active, inhibiting the formation of the REPTOR/REPTOR-BP complex by phosphorylating REPTOR and mediates its cytoplasmic retention by forming a docking site for 14-3-3 proteins. Upon TORC1 inhibition resulting from nutrient stress, REPTOR is recruited into the nucleus where it interacts with REPTOR-BP and together they maintain organismal metabolism by activating the expression of target stress response genes including those involved in glycogenesis and triglyceride biosynthesis. The complex also appears to negatively regulate some aspects of TORC1-dependent larval growth.

External Data

Subunit Structure (UniProtKB)

Interacts (via C-terminus) with REPTOR-BP (via C-terminus). Interacts with the TORC1 complex component raptor. Interacts (when phosphorylated) with 14-3-3zeta, this interaction may assist its cytoplasmic retention.

(UniProt, Q9VC61)

Post Translational Modification

Phosphorylation by the TORC1 kinase complex at Ser-527 and Ser-530 abolishes nuclear localization. Upon TORC1 inhibition, dephosphorylated in a mts/PP2a-dependent manner leading to nuclear localization.
