We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Jumping Translocation Breakpoint (JTB) is an orphan receptor that is conserved from nematodes to humans and whose gene expression in humans is strikingly upregulated in diverse types of cancers. Translocations occur frequently at the hJTB genomic locus, leading to multiple copies of a truncated JTB gene, which potentially encodes a soluble secreted ectodomain. In addition, JTB and its orthologs likely represent a unique and ancient protein family since homologs could not be identified by direct sequence comparison. In the present study, we have determined the NMR solution structure of the N-terminal ectodomain of human JTB, showing that its fold architecture is a new variant of a three-beta-strand antiparallel beta-meander. The JTB structure has a distant relationship to the midkine/pleiotrophin fold, particularly in the conservation of distinctive disulfide bridge patterns. The structure of this newly characterized small cysteine-rich domain suggests potential involvement of JTB in interactions with proteins or extracellular matrix and may help to uncover the elusive biological functions of this protein. | Jumping Translocation Breakpoint (JTB) is an orphan receptor that is conserved from nematodes to humans and whose gene expression in humans is strikingly upregulated in diverse types of cancers.
