Irs1 - insulin receptor substrate 1

Enables phosphatidylinositol 3-kinase binding activity and protein kinase binding activity. Involved in cellular response to fatty acid. Acts upstream of or within several processes, including cellular response to insulin stimulus; positive regulation of phosphatidylinositol 3-kinase activity; and protein kinase B signaling. Located in several cellular components, including ciliary basal body; nucleus; and plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Used to study type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in Alzheimer's disease; coronary artery disease; and type 2 diabetes mellitus. Orthologous to human IRS1 (insulin receptor substrate 1).
