ligandin

glu·ta·thi·one S-·trans·fer·ase

a class of enzymes that catalyzes the reaction of glutathione with an acceptor molecule (for example, an arene oxide) to form an S-substituted glutathione; a key step in detoxification of many substances; start of the mercapturic acid pathway.
Synonym(s): ligandin

ligandin

an hepatic transport protein; measurement of it in serum and urine may be a means of estimating the severity of hepatocellular necrosis.

Neonatal physiologic jaundice can be a result of increased bilirubin production secondary to accelerated destruction of erythrocytes or decreased excretory capacity secondary to low levels of ligandin which is a binding protein for bilirubin in hepatocytes and low activity of bilirubin-conjugating enzyme uridine diphosphoglucuronyltransferase (UDPGT).
Increased incidence of neonatal hyperbilirubinemia in preterm and low birth weight babies can be explained on the basis of hepatic immaturity, increased bilirubin load, decreased synthesis of ligandin (Y protein) and decreased UDPG (T) activity.

Intracellular transport of bilirubin from the hepatic plasma membrane to the endoplasmic reticulum, where conjugation occurs, is not well understood; however, cytosolic proteins (Y or ligandin Z or fatty-acid-binding protein) account for most of the intracellular bilirubin binding capacity.
