| Background Information | Human SECTM1 (secreted and transmembrance 1) is a type I transmembrane glycoprotein consisted of a 28 aa signal sequence, a 117 aa extracellular domain (ECD) with one potential N?linked glycosylation site, a 21 aa transmembrane sequence, and an 82 aa cytoplasmic sequence. It is localized in the Golgi apparatus and exists as a transmembrane and a soluble form. SECTM1 protein expression is detected in some myeloid cells, such as stimulated monocytes, immature monocyte?derived dendritic cells, and granulocytes. In the thymus, it is also expressed by epithelia and fibroblasts. Its expression is stimulated by IFN-gamma. Although its function is not well understood, the soluble N-terminus form of human SECTM1 demonstrates that it is a costimulatory ligand for human CD4 and CD8 T cell proliferation and cytokine production in CD7-dependent manner. |
