Background: Xg

Xg, also known as PBDX (pseudoautosomal boundary divided on the X chromosome), is a type I transmembrane glycoprotein that belongs to the CD99 family. It is an erythrocyte membrane protein that is used as the basis for the Xg blood group system. Mature Xg is a 26 kDa glycoprotein that consists of a 121 aa extracellular domain, a transmembrane segment, and a 17 aa cytoplasmic tail. Xg isoforms with either a 15 aa insertion or a deletion of nearly the entire ECD have been reported. Within the extracellular domain, human Xg shares 100% aa sequence identity with mouse Xg.
