Description:

The Notch receptors and their ligands are highly conserved from invertebrates to mammals. The Jagged-2 is one of the several Notch ligands identified. The binding to Notch receptor results in the proteolysis of Notch and movement of intracellular portion of Notch into the nucleus. This translocation triggers a series of signaling process. Jagged-2 is reported to be essential for the regulation of spermatogenesis.

Other Names:

HJ2, Jagged2, Jagged-2 precursor, JAG2

Structure:

A single pass transmembrane protein consisting of a large extracellular N-terminal which includes the DSL domain, followed by a tandem array of EGF-like repeats (ELRs) and cysteine-rich domain (CRD). After a single transmembrane domain (TM) is a short in

Distribution:

Testicular tissues and spermatids

Function:

The Notch receptors and their ligands are highly conserved signaling molecules throughout development. They regulate cell fate decision for various cell development, including myogenesis, neurogenesis, and lymphocyte development. There is growing evidence that signals transmitted through different Notch ligands can differentially affect the target cells. Notch1/Jagged-2 signaling system plays an important role for male germ cells to differentiate.

Ligand Receptor:

Notch receptors

Cellular Targets:

Skeletrophin binds the intracellular regions of Jagged-2, but not those of Delta-1,3,4, or Jagged-1.
