Insulin induced gene 1, also known as INSIG1, is a protein which in humans is encoded by the INSIG1 gene.
INSIG1 is short for insulin-induced gene 1; it is located on chromosome 7 (7q36). This human gene encodes for a 277 AA long transmembrane protein with probably 6 transmembrane domains. It is localized in the ER and seems to be expressed in all tissues, especially in liver.
