反应种属 | Human |
应用 | Western Blot(1 µg/mL) |
目标/特异性 | Detects human Gas6 in ELISAs and Western blots. Because this antibody preparation is a total IgG fraction, complete monospecificity cannot be assumed. |
使用方法 | Western Blot: 1 µg/mL Blockade of Receptor-ligand Interaction: In a functional ELISA, 1-5 µg/mL of this antibody will block 50% of the binding of 10 ng/mL of biotinylated Recombinant Human Gas6, lacking the Gla domain, to immobilized Recombinant Human Axl Fc Chimera (Catalog # 154-AL) coated at 2 µg/mL (100 µL/well). At 100 μg/mL, this antibody will block >90% of the binding. |

背景 | Gas6 (Growth Arrest Specific 6) is a multimodular protein that is upregulated by a wide variety of cell types in response to growth arrest (1). Gas6 and the structurally related Protein S are vitamin K-dependent and have an extensively gamma -carboxylated N-terminal Gla domain, four EGF‑like repeats, and a C-terminal region with homology to steroid hormone binding globulin (SHBG) (2). Human Gas6 is a 75 kDa protein that shares 77-79% aa sequence identity with mouse and rat Gas6, and 43% aa identity with human protein S (over the region expressed). Alternate splicing generates isoforms that lack the Gla domain and/or the spacer between the EGF‑like and SHBG regions. Gas6 binds and induces signaling through the receptor tyrosine kinases Axl, Dtk, and Mer (3-5). Human Gas6 interacts with both mouse and rat orthologs of these receptors (1). The full length isoform may be cleaved, resulting in release of the free SHBG region which can independently activate Axl (6). Shed soluble forms of Axl and Mer bind Gas6 and function as decoy receptors (7, 8). Gas6 induces a variety of responses, including prevention of apoptosis (9), cell proliferation (10), platelet-mediated thrombosis (11), retinal epithelial cell phagocytosis of outer rod segments (12), inhibition of VEGF-induced endothelial cell chemotaxis (13), and the differentiation and expansion of NK cell precursors (14). The affinity of Gas6 for phosphatidylserine likely contributes to its role in promoting the phagocytosis of apoptotic cells (15). Several of these effects have been shown to require gamma -carboxylation of the Gla domain (12, 16). |
