V-set domain-containing T-cell activation inhibitor 1 (VTCN1) is also known as Immune costimulatory protein B7-H4, Protein B7S1, T-cell costimulatory molecule B7x, B7H4, which belongs to the immunoglobulin superfamily and BTN/MOG family.
VTCN1 contains two Ig-like V-type (immunoglobulin-like) domains.
The expression of VTCN1 is up-regulated by IL6 and IL10 and is inhibited by GM-CSF and IL4 on antigen-presenting cells (APCs).
VTCN1 / B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity.
VTCN1 involved in promoting epithelial cell transformation.
特徴
This protein carries an Avi tag (Avitag) at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 28 kDa.
The protein migrates as 43-57 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
