Physical State: Liquid (sterile filtered)
Purity and Specificity: Recombinant full length human PI3K (p85β) was expressed by baculovirus in Sf9 insect cells using an N-Terminal his epitope. The purity was determined to be >85% by densitometry.
Background: Phosphatidylinositol 3-kinase (PI3K) is a lipid kinase that phosphorylates the inositol ring of phosphatidylinositol and related lipid products at the 3-prime position. PI3K p85 subunit which is the regulatory subunit of PI3K and consists of 2 closely related proteins, p85-alpha and p85-beta (1). The activation of PI3K signaling in influenza A virus-infected cells is important for efficient virus replication (2). PI3K signaling in T cells can lead to organ-specific autoimmunity and the class IA PI3K-deficient mice manifest the cardinal features of human primary Sjogren’s syndrome-like disease (3). PI3k (p85 beta) Protein is ideal for investigators involved in Signaling Proteins, Cellular Proteins, AKT/PKB Pathway, Angiogenesis, Apoptosis/Autophagy, Cancer, Cardiovascular Disease, Inflammation, Invasion/Metastasis, Lipid Kinases, Metabolic Disorder, Neurobiology, NfkB Pathway, and WNT Signaling research.
