Furry Homolog (FRY)

FRY belongs to the furry protein family. Plays a key role in maintaining the integrity of polarized cell extensions during morphogenesis, regulates the actin cytoskeleton and plays a key role in patterning sensory neuron dendritic fields by promoting avoidance between homologous dendrites as well as by limiting dendritic branching. May function as a transcriptional activator.A transcriptional corepressor, Xenopus furry (Xfurry), is expressed in the chordamesodermal region and induces secondary dorsal axes when overexpressed on the ventral side of the embryo. The N-terminal furry domain functions as a repressor, and the C-terminal leucine zipper (LZ) motifs /coiled-coil structure, found only in vertebrate homologs, contributes to the nuclear localization.
