Recombinant Human V-type immunoglobulin domain-containing suppressor of T-cell activation (VSIR), Truncated

Uniprot Id

Q9H7M9

Target Species

Human

Target Name

VSIR

Target Full Name

V-type immunoglobulin domain-containing suppressor of T-cell activation

Target Function

Immunoregulatory receptor which inhibits the T-cell response. May promote differentiation of embryonic stem cells, by inhibiting BMP4 signaling. May stimulate MMP14-mediated MMP2 activation.

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein.

Target Tissue Specificity

Expressed in spleen. Detected on a number of myeloid cells including CD11b monocytes, CD66b+ neutrophils, at low levels on CD4+ and CD8+ T-cells, and in a subset of NK cells. Not detected on B cells (at protein level). Expressed at high levels in placenta

Target Research Area

Cardiovascular

Target Background

Enables endopeptidase activator activity; enzyme binding activity; and identical protein binding activity. Involved in several processes, including negative regulation of cytokine production; positive regulation of macromolecule metabolic process; and regulation of T cell activation. Located in plasma membrane.
