Originally discovered in Xenopus laevis as a cement gland differentiation regulator <ref>PMID: 31644305</ref>, <scene name='87/872187/Agr2_full/1'>Anterior Gradient Protein 2</scene> (AGR2) in humans is a protein chaperone ([[chaperones]]) involved in '''proteostasis''', mainly for proteins expressed in epithelial cells, such as in the esophagus or lungs<ref>PMID:33005802</ref>. AGR2, composed of 175 amino acids, belongs to the protein disulfide isomerase family ([https://www.uniprot.org/uniprot/P07237 PDI]). | Originally discovered in Xenopus laevis as a cement gland differentiation regulator <ref>PMID: 31644305</ref>, <scene name='87/872187/Agr2_full/1'>Anterior Gradient Protein 2</scene> (AGR2) in humans is a protein chaperone ([[chaperones]]) involved in '''proteostasis''', mainly for proteins expressed in epithelial cells, such as in the esophagus or lungs<ref>PMID:33005802</ref>.

The AGR2 protein can form complexes with [https://www.uniprot.org/uniprot/Q9Y230 Reptin] ([[2cqa]]) which is recognized as an '''anti-oncogene'''. However, it binds more easily when the protein is in dimeric form. Thus, a mutation on (<scene name='87/872187/Agr2_e60/2'>E60</scene>) site, giving the protein a monomeric form, would reduce cancer repression by Reptin. | The AGR2 protein can form complexes with [https://www.uniprot.org/uniprot/Q9Y230 Reptin] ([[2cqa]]) which is recognized as an '''anti-oncogene'''.

Finally, the expression of AGR2 in breast cancer patients confers chemoresistance to cancer cell growth inhibitors such as Tamoxifen, the mechanism is still unclear.<ref>PMID: 25937245</ref> | Finally, the expression of AGR2 in breast cancer patients confers chemoresistance to cancer cell growth inhibitors such as Tamoxifen, the mechanism is still unclear.<ref>PMID: 25937245</ref> | ||
