Summary: Predicted to enable L-leucine binding activity and oxidoreductase activity, acting on peroxide as acceptor. Involved in cellular response to amino acid stimulus; negative regulation of TORC1 signaling; and negative regulation of cell growth. Acts upstream of or within regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction. Predicted to be located in cytoplasm; fibrillar center; and nucleoplasm. Predicted to be part of GATOR2 complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and integumental system. Orthologous to human SESN1 (sestrin 1). [provided by Alliance of Genome Resources, Dec 2024]

Sestrins are critical mediators of exercise benefits. Genetic ablation of Sestrins prevents mice from acquiring metabolic benefits of exercise and improving their endurance through training. Sestrin upregulation mimics both molecular and physiological effects of exercise, suggesting that it is a major effector of exercise metabolism. AKT and PGC1alpha are critical for the Sestrin effects in extending endurance.

By upregulating AMPK and autophagic activities and suppressing mammalian target of rapamycin complex 1 and oxidative stress, sestrins counteract detrimental effects of doxorubicin on cardiomyocytes.

Sestrin 1 targets at the AMPK/mTORC1/autophagy pathway to inhibit cardiac hypertrophy by interaction with AMPK which is responsible for autophagy regulation. Taken together, our data indicate that Sestrin 1 regulates AMPK/mTORC1/autophagy axis to attenuate cardiac hypertrophy.
Title: Sestrin 1 ameliorates cardiac hypertrophy via autophagy activation.
Study found that Sestrins (1,2 and 3) can inhibit mTORC1 signaling in the absence of AMPK or TSC2. Surprisingly, when coexpressed with a GTP-bound constitutively active form of RagB (RagBQ99L), Sestrins potentiate mTORC1 signaling in the absence of amino acids.
Title: Sestrins function as guanine nucleotide dissociation inhibitors for Rag GTPases to control mTORC1 signaling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
