Anti-SEMA4C antibody produced in rabbit

General description

SEMA4C (semaphorin 4C) is a transmembrane neural protein which belongs to the family of semaphorin proteins. It has a cytoplasmic domain made of 146 amino acids, which has a proline rich region. The C-terminal contains a PDZ binding domain. This protein is expressed in neurons of embryos, and predominantly in postnatal and adult brain.

Immunogen

Semaphorin-4C precursor recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

The function of SEMA4C (semaphorin 4C) is not well defined. It functions as a ligand for cell-sruface signaling by interacting with SEMCAP-1 (SEMA4C cytoplasmic domain-associated protein). It might also be responsible for axonal guidance, by forming clusters with SEMCAP-1, which in turn acts as ligand for receptors on adjacent cells. SEMA4C is highly expressed in adult brains, which suggests that this protein might be involved in synaptic plasticity. It might act as a bi-directional ligand for PSD-95 (postsynaptic density protein-95), in cortical neurons. Haploinsufficiency of this gene might be linked to Cri-du-chat syndrome, by causing abnormal brain development. SEMA4C might be involved in G-protein signaling through its interaction with SEMCAP-1. It is up-regulated in esophageal, gastric and rectal cancer, and might be responsible for the invasion and lymphatic metastasis of the same. It is involved in epithelial-mesenchymal transition in renal tubular epithelial cells, through TGF-β1-induced mitogen-activated protein kinase (MAPK) activation.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Linkage

Corresponding Antigen APREST72185.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
