The lirst extracellular domain of the cadherins has been shown to exhibit extensive sequence homology with the
amino termini of the HA1 chains of influenza strain A hemagglutinins. These regions of homology are known to be
functionally important in both the cadherins and the hemagglutinins. The homologous regions harbor the tripeptidc
HAL', which has been identified as being the cadherin cell adhesion recognition sequence. Here we report that members
of the rapidly expanding family of fibroblast growth factor receptors also possess HAV-containing regions. These
regions are homologous to the HAV-containing regions present within both the hemagglutinins and the cadherins and
appear to be involved in regulating the function of the fibroblast growth factor receptors. We speculate that the HAV
motif may represent an evolutionarily conserved amino acid sequence that will prove to be functionally important in a
wide variety of proteins. 6 1992 Academic Press, Inc
