Stabilin-1(STAB1) or common lymphatic endothelial and vascular endothelial receptor-1 (CLEVER-1) is a large, multidomain, type I transmembrane protein. It is expressed in cardiac and skeletal muscle; by macrophages in skin, gut, placenta, and pancreas; and in liver, spleen, bone marrow, and lymph nodes by sinusoidal endothelial cells. Also known as FEEL-1, it contains a proteoglycan-link protein-like sequence, 7 fasciclin domains, 2 RGD (Arg-Gly-Asp ) motifs, and 22 epidermal growth factor-like repeats.
Synonyms: Anti-FEEL-1 antibody produced in rabbit; Anti-Fasciclin, EGF-like, laminin-type EGF-like and link domain-containing scavenger receptor 1 antibody produced in rabbit; Anti-MS-1 antigen antibody produced in rabbit; Anti-Stabilin-1 precursor antibody produced in rabbit

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: Stabilin-1(STAB1) or common lymphatic endothelial and vascular endothelial receptor-1 (CLEVER-1) helps in leukocyte adhesion and migration as well as regulation of angiogenesis. In human macrophages, it is responsible for trafficking between trans-Golgi network and early/sorting endosomes. In macrophages and endothelial cells, it mediates endocytosis by acting as an endocytic receptor. Stabilin-1 also acts as a receptor for acetylated low density lipoprotein (Ac-LDL), placental lactogen, SPARC protein, apoptotic bodies and bacteria, and thus is responsible for the scavenging action of macrophages. It is also responsible for the intracellular sorting of chitinase-like protein SI-CLP, which is endogenous in nature. Recent studies suggest that CLEVER-1 mediates metastasis of breast cancer and head and neck squamous cell carcinoma via the lymphatic system. Stabilin-1 is used as a marker for the diagnosis of cutaneous non-Langerhans cell histiocytoses.
