Summary: Involved in cellular response to amino acid stimulus; negative regulation of TORC1 signaling; and regulation of skeletal muscle tissue regeneration. Predicted to be located in late endosome membrane and lysosomal membrane. Predicted to be part of lysosomal proton-transporting V-type ATPase complex. Is expressed in several structures, including central nervous system; dorsal root ganglion; and sensory organ. Orthologous to human SPAAR (small regulatory polypeptide of amino acid response).

The LINC00961 transcript and its encoded micropeptide, small regulatory polypeptide of amino acid response, regulate endothelial cell function.
Title: The LINC00961 transcript and its encoded micropeptide, small regulatory polypeptide of amino acid response, regulate endothelial cell function.
data provide a mechanism by which mTORC1 activation may be finely regulated in a tissue-specific manner in response to injury, and a paradigm by which lncRNAs encoding small polypeptides like SPAR can modulate general biological pathways and processes to facilitate tissue-specific requirements, consistent with their restricted and highly regulated expression profile
Title: mTORC1 and muscle regeneration are regulated by the LINC00961-encoded SPAR polypeptide.

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.
