Leucine-rich repeat transmembrane protein FLRT1 (FLRT1)

Plays a role in fibroblast growth factor-mediated signaling cascades that result in the activation of MAP kinases. Promotes neurite outgrowth through FGFR1-mediated activation of downstream MAP kinases.

Promotes an increase both in neurite number and in neurite length. May play a role in cell-cell adhesion and cell guidance via its interaction with ADGRL1/LPHN1 and ADGRL3.
