Summary: Predicted to enable inorganic diphosphatase activity and magnesium ion binding activity. Predicted to be involved in COPII-coated vesicle cargo loading and phosphate-containing compound metabolic process. 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 cytosol. Orthologous to human SAR1A (secretion associated Ras related GTPase 1A). [provided by Alliance of Genome Resources, Apr 2022]

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.
