Summary: Predicted to enable G protein activity; amino acid sensor activity; and inorganic diphosphate phosphatase activity. Predicted to be involved in several processes, including COPII-coated vesicle budding; cellular response to leucine starvation; and negative regulation of TORC1 signaling. Predicted to act upstream of or within negative regulation of cargo loading into COPII-coated vesicle and vesicle-mediated transport. Predicted to be located in Golgi apparatus and sarcoplasmic reticulum. Predicted to be part of COPII vesicle coat. Predicted to be active in endoplasmic reticulum exit site and lysosomal membrane. Orthologous to several human genes including PPA1 (inorganic pyrophosphatase 1). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Sar1 recruitment to the endoplasmic reticulum-membrane is sensitive to H89-sensitive kinase activation, indicating the first step in transport vesicle formation occurs under kinase regulation
Title: Sar1 translocation onto the ER-membrane for vesicle budding has different pathways for promotion and suppression of ER-to-Golgi transport mediated through H89-sensitive kinase and ER-resident G protein.
beta-tubulin is one of downstream effectors of H89-sensitive kinase and suppression of endoplasmic reticulum (ER)-coupled beta-tubulin phosphorylation decreases Sar1 translocation onto the ER.
Title: H89 sensitive kinase regulates the translocation of Sar1 onto the ER membrane through phosphorylation of ER-coupled β-tubulin.

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.
