UniProtKB - Q70AK3 (FLRT3_XENLA)
Protein
Leucine-rich repeat transmembrane protein FLRT3
Gene
flrt3
Organism
Xenopus laevis (African clawed frog)
Status
Functioni
Functions in cell-cell adhesion, cell migration and axon guidance, exerting an attractive or repulsive role depending on its interaction partners (By similarity). Modulates cadherin-dependent cell-cell adhesion and cell sorting (PubMed:20027292, PubMed:19492039). Plays a role in the spatial organization of brain neurons. Plays a role in vascular development. Plays a role in cell-cell adhesion via its interaction with latrophilins that are expressed at the surface of adjacent cells. Mediates axon attraction towards cells expressing ntn1. Mediates axon growth cone collapse and plays a repulsive role in neuron guidance via its interaction with unc-5 family members. Plays a role in the regulation of the density of glutamaergic synapses (By similarity). Plays a role in signaling cascades downstream of fgfr1, and possibly also other fgfr family members (PubMed:14688794). Plays a role in embryonic morphogenesis, but not in embryonic patterning (PubMed:19492039).By similarity3 Publications
