Description
Catalogue Number 09-107
Description Anti-phospho-Raptor (Ser877) Antibody
Alternate Names
  • P150 target of rapamycin (TOR)-scaffold protein
  • p150 target of rapamycin (TOR)-scaffold protein containing WD-repeats
  • regulatory associated protein of mTOR
Background Information Raptor is a subunit of mTORC1 which regulates cell growth and survival in response to nutrient and hormonal signals. mTORC1 is activated in response to growth factors or amino-acids. Within mTORC1, Raptor positively regulates mTORC1 activity and functions as a scaffold for recruiting mTORC1 substrates

Antibody Type Polyclonal Antibody
Entrez Gene Number
Entrez Gene Summary This gene encodes a component of a signaling pathway that regulates cell growth in response to nutrient and insulin levels. The encoded protein forms a stoichiometric complex with the mTOR kinase, and also associates with eukaryotic initiation factor 4E-binding protein-1 and ribosomal protein S6 kinase. The protein positively regulates the downstream effector ribosomal protein S6 kinase, and negatively regulates the mTOR kinase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq].

Purification Method Affinity Purfied
UniProt Number
UniProt Summary FUNCTION: Participates in the FRAP1 pathway and associates in a near stoichiometric ratio with FRAP1 to form a nutrient-sensitive complex (NSC). Plays a pivotal role as a scaffold protein in the FRAP1-signaling pathway and this interaction is essential for the catalyzed phosphorylation of EIF4EBP1. Has a positive role in nutrient-stimulated signaling to the downstream effector RPS6KB1. Under nutrient-deprived conditions, serves as a negative regulator of FRAP1 kinase activity. Regulation of the interaction with FRAP1 is a critical mechanism by which cells coordinate the rate of cell growth and maintenance of cell size with different environmental conditions.

SIZE: 1335 amino acids; 149038 Da

SUBUNIT: Binds directly 4EBP1 and RPS6KB1 independently of its association with FRAP1. Binds preferentially to poorly or non- phosphorylated form of EIF4EBP1, and this binding is critical to the ability of FRAP1 to catalyze phosphorylation. Complex with FRAP1 physically interacts under both leucine-rich and -poor conditions and therefore in at least two nutrient-determined states with different stability.

TISSUE SPECIFICITY: Highly expressed in skeletal muscle, and in a lesser extent in brain, lung, small intestine, kidney and placenta.

SIMILARITY: Contains 7 WD repeats.

MISCELLANEOUS: Rapamycin destabilizes the interaction with FRAP1 regardless of nutrient availability, and its potency for dissociation is increased under nutrient-rich conditions. This action uncouples FRAP1 from its substrates, and inhibits FRAP1 signaling without altering its intrinsic catalytic activity.
