Regenerating islet-derived protein 3 alpha (or Regenerating islet-derived protein III-alpha) formerly known as HIP/PAP (Hepatocarcinoma-Intestine-Pancreas/Pancreatitis-Associated Protein) and peptide 23[5] is a protein that in humans is encoded by the REG3Agene.[6][7]
This gene encodes a pancreaticsecretory protein that may be involved in cell proliferation or differentiation. It has similarity to the C-type lectin superfamily. The enhanced expression of this gene is observed during pancreatic inflammation and liver carcinogenesis. Multiple alternatively spliced transcript variants encoding the same protein have been described for this gene but the full length nature of some transcripts is not yet known.[7]
