Jumping translocation breakpoint

The jumping translocation breakpoint protein (JTB), also known as prostate androgen-regulated protein (PAR), is a protein that in humans is encoded by the JTB gene.[5][6] It is an orphan receptor with unknown function.[7]

PDBsumstructure summary

The JTB family of proteins contains several jumping translocation breakpoint proteins or JTBs. Jumping translocation (JT) is an unbalanced translocation that comprises amplified chromosomal segments jumping to various telomeres. JTB has been found to fuse with the telomeric repeats of acceptor telomeres in a case of JT. Homo sapiens JTB (hJTB) encodes a transmembrane protein that is highly conserved among divergent eukaryotic species. JT results in a hJTB truncation, which potentially produces an hJTB product devoid of the transmembrane domain. hJTB is located in a gene-rich region at 1q21, called epidermal differentiation complex (EDC).[5] JTB has also been implicated in prostatic carcinomas.[8]
