Monoclonal Anti-C10orf54 (mouse IgG1 isotype) is derived from the hybridoma OR.4 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide.C10orf54 (Chromosome 10 open reading frame 54) is also referred to as GI24, B7 member B7-H5, VISTA (V-domain Ig suppressor of T cell activation) and Dies1. It is a novel surface glycoprotein belonging to the B7 immunoglobulin superfamily. It consists of a single IgV domain with 3 additional cysteine residues and a cytoplasmic tail. It is expressed on mature myeloid APCs (antigen-presenting cells) including peritoneal macrophages, mature BMDC (bone marrow-derived dendritic cell), neutrophils and CD11c+ DCs, and to a lesser quantity in T cells and activated Treg cells.
Immunogen
synthetic peptide corresponding to a sequence at the internal region of human C10orf54
Application
Phosphotyrosine antibody inhibitor has been used in flow-cytometry and immunohistochemistry.
Biochem/physiol Actions
Studies suggest that C10orf54 (Chromosome 10 open reading frame 54) functions as a co-inhibitory ligand and restricts the mechanism of T cell proliferation and cytokine production. It was also suggested that C10orf 54 acts as a positive regulator as well as a substrate of MT1-MMP (trans-membrane type 1-matrix metalloproteinase) during tumor growth of collagen matrix, which regulates invasive growth.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Co-signaling molecules are surface glycoproteins that positively or negatively regulate the T cell response to antigen. Co-signaling ligands and receptors crosstalk between the surfaces of antigen-presenting cells (APCs) and T cells, and modulate the ultimate magnitude and quality of T

The immunoglobulin (Ig) superfamily consists of many critical immune regulators, including the B7 family ligands and receptors. In this study, we identify a novel and structurally distinct Ig superfamily inhibitory ligand, whose extracellular domain bears homology to the B7 family
GI24, an immunoglobulin superfamily member, has been cloned from a placenta cDNA library as a gene product that promoted activation of matrix metalloproteinase (MMP)-2 mediated by membrane type (MT) 1-MMP. Co-expression of GI24 with MT1-MMP in HEK293T cells increased the
