NCIt definition : Neurexin-3-beta (637 aa, 69 kDa) is encoded by the human NRXN3 gene. This protein
plays a role in cell adhesion.;
NCIt note : Neurexin-3-beta is proccessed by alpha-secretase, which leads to the formation of
an extracellular soluble form and a C-terminal membrane-embedded fragment (CTF). Proteolysis
of the CTFs by gamma-secretase releases intracellular domains (ICDs) and extracellular
peptides.;
