What is "uteroglobin"

Uteroglobin, also known as secretoglobin family 1A member 1 (SCGB1A1), is a protein that in humans is encoded by the SCGB1A1 gene.

SCGB1A1 is the founding member of the secretoglobin family of small, secreted, disulfide-bridged dimeric proteins found only in mammals. This antiparallel disulfide linked homodimeric protein is multifunctional and found in various tissues in various names such as: Uteroglobin (UG, UGB), Uteroglobin-like Antigen (UGL), Blastokinin, club cell secretory protein (CCSP), Clara cell 16 kD protein (17 in rat/mice), club Cell-Specific 10 kD Protein (CC10), human protein 1, urine protein 1 (UP-1), polychlorinated biphenyl-binding protein (PCB-BP), human club Cell Phospholipid-Binding Protein (hCCPBP), Secretoglobin 1A member 1 (SCGB1A1).

This protein is specifically expressed in club cells in the lungs.
