Summary: Enables growth factor activity; identical protein binding activity; and protein phosphatase binding activity. Involved in several processes, including cellular response to gastrin; liver regeneration; and positive regulation of epithelial cell proliferation. Located in several cellular components, including dendrite membrane; neuronal cell body membrane; and zymogen granule. Part of protein-containing complex. Biomarker of colon cancer and myocardial infarction. Human ortholog(s) of this gene implicated in type 1 diabetes mellitus. Orthologous to several human genes including REG1A (regenerating family member 1 alpha). [provided by Alliance of Genome Resources, Dec 2024]

The positive correlation between Reg1a and Tgfb1 genes expression was determined in the dynamics of stress-induced gastric lesions development and healing, which may indicate the involvement of Tgfb1 in acceleration of lesions healing.

The pancreas reacts to remote lesions and septic insults in mice and rats with increased PSP synthesis, while PAP is selectively responsive to septic events. Furthermore, our results suggest that serum PSP in septic patients is predominantly derived through an acute phase response of the pancreas.
Title: The pancreas responds to remote damage and systemic stress by secretion of the pancreatic secretory proteins PSP/regI and PAP/regIII.
Alox15 mRNA levels were 4 times higher in iron-deficient than in iron-adequate pancreas and that Reg1a, Reg3a, and Reg3b mRNA levels were 17-36 times higher in iron-overloaded pancreas.
Title: Microarray analysis of rat pancreas reveals altered expression of Alox15 and regenerating islet-derived genes in response to iron deficiency and overload.
These results strongly suggest that the combined stimulation of IL-6 and glucocorticoids induces the activation of both Reg and HGF genes.

Reg I expression in acinar cells is important in maintaining pancreatic cell lineage, and when decreased, cells can dedifferentiate and move toward becoming other pancreatic cells.
Title: Pancreatic regenerating gene I and acinar cell differentiation: influence on cellular lineage.
These results demonstrate that Reg I is significantly upregulated in the liver of the 2-AAF/PH rat model, accompanied by the formation of bile ductules during liver regeneration.
Title: Expression and localization of regenerating gene I in a rat liver regeneration model.
Depletion of the acinar product reg I is associated with the pathogenesis of impaired glucose tolerance of pancreatitis-associated diabetes and aging, and replacement therapy could be useful in these patients.

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.
