LRRC4 Antibody

LRRC4 (Leu-rich repeat/LRR-containing glycoprotein 4), LRRC4B and LRRC4C, also called NGL-2 (netrin-G ligand-2), NGL-3 and NGL-1, respectively, are post-synaptic adhesion molecules of the LRR protein family that induce excitatory synapse formation. Mature LRRC4 family members are type I transmembrane proteins with an extracellular region that contains nine LRRs, a C2-type Ig-like domain, and a Thr-rich segment. LRRC4 family members share ~55% aa identity, but each recognizes different ligands. LRRC4 and LRRC4C recognize Netrin-G2 and Netrin-G3, respectively, while LRRC4B recognizes the receptor tyrosine phosphatases LAR/PTPRF, PTPR delta and PTPR sigma.
