Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt), and Mer (human and mouse homologues of chicken c-Eyk) constitute a subfamily of the receptor tyrosine kinases (1, 2). The extracellular domains 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. The mouse Axl cDNA encodes an 888 amino acid (aa) precursor that includes an 18 aa signal sequence, a 427 aa extracellular domain, a 21 aa transmembrane segment, and a 422 aa cytoplasmic domain. The extracellular domains of mouse and human Axl share 81% aa sequence identity. These receptors bind the vitamin K-dependent protein growth arrest specific gene 6 (Gas6) which is structurally related to the anticoagulation factor protein S. Binding of Gas6 induces receptor autophosphorylation and downstream signaling pathways that can lead to cell proliferation, migration, or the prevention of apoptosis (3). This family of tyrosine kinase receptors is involved in hematopoiesis, embryonic development, tumorigenesis, and regulation of testicular functions.

Scientific Data Images for Mouse Axl Antibody
Axl in Mouse Kidney.
Axl was detected in immersion fixed paraffin-embedded sections of mouse kidney using Goat Anti-Mouse Axl Antigen Affinity-purified Polyclonal Antibody (Catalog # AF854) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell membranes in convoluted tubules.

Detection of Mouse Axl by Immunohistochemistry
Renal microvascular expression of Axl, Fyn, and Lck in the kidney in unstimulated control and TNF-alpha -exposed mice. Images of kidney cryosections of mice exposed to 200 ng TNF-alpha for 2 h showing localisation of (A) Axl (B) Fyn and (C) Lck. Representative images are shown. Arrowheads indicate different microvascular beds, arterioles (A), glomeruli (g), peritubular capillaries (ptc), and venules (v). Original magnification is ×200. Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/36532777), licensed under a CC-BY license.

Kinase presence and activity in TNF-alpha -stimulated HUVEC. The influence of different durations of TNF-alpha (10 ng/ml) stimulation on the phosphorylation and total protein expression of (A) p65 and (B) ERK1/2 determined in HUVEC by immunoblotting. Quantification and normalisation of phosphorylated protein to total protein is shown as fold-change to unstimulated control. (C) Selection of three kinases as potential targets based on time-course data of the mean specificity score and mean kinase statistic (see Materials and Methods). The mean specificity score is based on peptide phosphorylation patterns relative to the unstimulated control condition and represents the likelihood of a kinase to be present (gradation of red). The mean kinase statistic indicates the predicted activity of the kinase relative to untreated control (gradation from blue, less active, to red, highly active). (D) Immunoblot of total HUVEC protein lysates showing presence of Axl and Fyn in control conditions or following 2 h TNF-alpha stimulation in HUVE. (E) Immunoblot of total HUVEC protein lysates showing absence of Lck in control conditions or following 2 h TNF-alpha stimulation in HUVEC. n = 3 independent experiments.
