A, Xenopus/Amphibian,L (A, Xenopus/Amphibian,L receptor tyrosine kinase) is a member of the receptor tyrosine kinase subfamily. Although it is similar to other receptor tyrosine kinases, this protein represents a unique structure of the e, Xenopus/Amphibian,tracellular region that ju, Xenopus/Amphibian,taposes IgL and FNIII repeats. It transduces signals from the e, Xenopus/Amphibian,tracellular matri, Xenopus/Amphibian, into the cytoplasm by binding growth factors like vitamin K-dependent protein growth-arrest-specific gene 6. It is involved in the stimulation of cell proliferation and can also mediate cell aggregation by homophilic binding.
