NCIt definition : Human FAT1 wild-type allele is located in the vicinity of 4q35 and is approximately
139 kb in length. This allele, which encodes protocadherin Fat 1 protein, plays a
role in both cellular polarization and cell adhesion.;
NCIt note : This gene is expressed at high levels in a number of fetal epithelia. Its product
probably functions as an adhesion molecule and/or signaling receptor, and is likely
to be important in developmental processes and cell communication.;
