Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; enzyme binding activity; and phosphatidylinositol 3-kinase regulatory subunit binding activity. Involved in several processes, including cellular response to hexose stimulus; cellular response to nutrient levels; and positive regulation of macromolecule biosynthetic process. Acts upstream of or within cellular response to leukemia inhibitory factor; epithelial cell maturation; and exocrine pancreas development. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; sensory organ; and skeletal system. Used to study inflammatory bowel disease. Orthologous to human XBP1 (X-box binding protein 1).
