Background: SIT1

SIT1 (SHP-2-interacting transmembrane adapter 1; also signaling threshold-regulating transmembrane adapter 1) is a 35‑40 kDa type I transmembrane glycoprotein that belongs to a diverse group of transmembrane adapter proteins. It is expressed on thymocytes, plasma cells and T cells. When engaged, SIT1 downregulates TCR signaling. Mature human SIT1 is 172 amino acids (aa) in length. It contains a short extracellular domain (aa 25‑40) that undergoes homodimerization and an extensive intracellular region (aa 62‑196) that contains three key phosphorylation sites (Tyr90/169/188). Over aa 65‑196, human SIT1 is 86% and 80% aa identical to canine and mouse SIT1, respectively.
