Background

Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt) and Mer (human and mouse homologues of chicken c-Eyk) constitute a new receptor tyrosine kinase subfamily (1, 2). The overall genomic structure of Dtk is virtually identical to that determined for the human UFO gene. This particular genomic organization is likely to have been duplicated and closely maintained throughout evolution (3). The extracellular domain of these proteins contain two Ig-like motifs and two fibronectin type III motifs. This characteristic topology is also found in neural cell adhesion molecules and in receptor tyrosine phosphatases (1). All three receptors bind the vitamin K-dependent protein growth-arrest specific gene 6 (Gas6) which is structurally related to the anti-coagulation factor protein S (1, 2). The binding affinities for Gas6 is in the order of Axl > Dtk > Mer (1). Gas6 binding induces tyrosine phosphorylation and down-stream signaling pathways that can lead to cell proliferation, migration, or the prevention of apoptosis (1, 2). Dtk is widely expressed during embryonic development. In adults, Dtk is predominantly expressed in neurons in restricted regions of the brain (4). The full length of Human DTK is 428 amino acids, with 387 amino acid signal sequence in the mature extracellular domain. The ECD of human DTK has 7 glycosylation sites. Within the ECD, human DTK shares 85% sequence identity with both mouse and rat DTK.
