CRYSTAL STRUCTURE OF THE PHOSPHOINOSITOL (3,4)-BISPHOSPHATE BINDING PH DOMAIN OF TAPP1 FROM HUMAN.
Overview
Phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P(3)] and its, immediate breakdown product PtdIns(3,4)P(2) function as second messengers, in growth factor- and insulin-induced signalling pathways. One of the ways, that these 3-phosphoinositides are known to regulate downstream signalling, events is by attracting proteins that possess specific PtdIns-binding, pleckstrin homology (PH) domains to the plasma membrane. Many of these, proteins, such as protein kinase B, phosphoinositide-dependent kinase 1, and the dual adaptor for phosphotyrosine and 3-phosphoinositides (DAPP1), interact with both PtdIns(3,4,5)P(3) and PtdIns(3,4)P(2) with similar, affinity. Recently, a new PH-domain-containing protein, termed tandem, PH-domain-containing protein (TAPP) 1, was described which is the ... [(full description)]
