背景介绍 Mammalian PTPases can be subdivided into 1 of 2 broad categories: transmembrane receptor PTPases and intracellular PTPases. PTPN11 is one of the 2 closely related mammalian intracellular PTPases whose sequences encode 2 tandem SRC homology 2 (SH2) domains that are located at the amino-terminal side of a single PTPase catalytic domain. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. 产品介绍 Human recombinant SHP-2, also known as PTPN11 (protein tyrosine phosphatase N11), full length (a.a. 2-593 (end) with N-terminal His-tag, Genbank accession number NM_002834, MW=70 kDa, expressed in an E. coli expression system.
