Location:

Chr: 5 Mapping Details/Browsers

Description:

Predicted to have transmembrane receptor protein tyrosine kinase activity. Involved in convergent extension; ephrin receptor signaling pathway; and vasculature development. Predicted to localize to integral component of plasma membrane and receptor complex. Is expressed in several structures, including axis; cardiovascular system; digestive system; nervous system; and neural tube. Used to study lymphatic system disease. Human ortholog(s) of this gene implicated in hereditary lymphedema. Orthologous to human EPHB4 (EPH receptor B4).
