What's a GeneRIF?

Our findings suggest a parallel increase in secretory activity between N-glycosylated and nonglycosylated a-amylase after b-adrenergic receptor activation.
Title: Parallel increase in secretory activity between N-glycosylated and nonglycosylated α-amylase without protein synthesis after short-term β-adrenergic receptor activation in isolated rat parotid acinar cells.
These results indicate that mucin plays an important role in the preservation of the mucosal barrier and that ischemia but not digestive enzymes disturbs mucin integrity, while digestive enzymes actively mediate epithelial cell disruption.
Title: Breakdown of mucin as barrier to digestive enzymes in the ischemic rat small intestine.
EPI64 acted as a physiological Rab27-GAP that enhanced GTPase activity of Rab27 in response to IPR stimulation, and that this activity is required for IPR-induced amylase release.
Title: EPI64 protein functions as a physiological GTPase-activating protein for Rab27 protein and regulates amylase release in rat parotid acinar cells.
Amylase-positive cells constitute an additional subset of taste receptor cells also associated with chemoreceptorial and/or secretory molecules, confirming the occurrence of various pathways in taste buds.
Title: Amylase expression in taste receptor cells of rat circumvallate papillae.
Increased salivary amylase was detected in sera of isoproterenol-treated animals, suggesting increased routing of the regulated secretory proteins to the basolateral pathway.
Title: Isoproterenol increases sorting of parotid gland cargo proteins to the basolateral pathway.
the HCO3-anion participates in the secretory sequence at sites distal to the identification of secretagogues in both endocrine and exocrine cells, the absence of extracellular bicarbonate is shown to decrease by about 50% basal alpha-amylase secretion

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.
