efn-3 encodes a potential GPI-modified ephrin that is, with EFN-2, is required for normal epidermal organization in the male tail; EFN-3, along with EFN-1 and EFN-2, activates the VAB-1 tyrosine kinase in vivo and binds it in vitro, and has a minor role in embryonic epiboly.
Predicted to enable ephrin receptor binding activity. Predicted to be involved in axon guidance and ephrin receptor signaling pathway. Predicted to be located in plasma membrane. Human ortholog(s) of this gene implicated in craniofrontonasal syndrome; dysostosis; and stomach cancer. Is an ortholog of human EFNB1 (ephrin B1).
Sequence connection from [Wang X, Culotti JG, Pawson T]
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
