* Information From OMIM

Function: Arregui et al. (2000) demonstrated that cell-permeable (Trojan) peptides containing the third helix of the antennapedia homeodomain fused to a peptide mimicking the juxtamembrane (JMP) region of the cytoplasmic domain of N-cadherin (CDH2; OMIM:114020) result in the inhibition of both CDH2 and ITGB1 function. Microscopic analysis showed that expression of JMP, which binds to the cytoplasmic domain of CDH2, results in a reduction of neurite outgrowth on cadherin substrates. Treatment of cells with JMP resulted in the release of FER (OMIM:176942) from the cadherin complex and its accumulation in the integrin complex. The accumulation of FER in the integrin complex and the inhibitory effects of JMP could be reversed with a peptide that mimics the first coiled-coil domain of FER. The results suggested that FER mediates crosstalk between CDH2 and ITGB1.
