EXTL2 (Exostosin-Like Glycosyltransferase 2): EXTL2 is a gene encoding a glycosyltransferase involved in the biosynthesis of heparan sulfate, a critical component of the extracellular matrix. Heparan sulfate is known to interact with various growth factors and signaling molecules, affecting processes like cell proliferation, adhesion, and differentiation. EXTL2's role in heparan sulfate synthesis highlights its significance in development and tissue homeostasis....
