背景介绍 GCK is a serine/threonine protein kinase that is activated by TNFα and interacts with the TNF receptor-associated factor 2 (TRAF2). GCK is upstream of MAP kinases and particularly activates the SAPK pathway (1). Although GCK is found in many tissues, its expression in lymphoid follicles is restricted to the cells of germinal centre, where it may participate in B-cell differentiation. A mouse protein Rab8ip that has high homology to GCK can interact with the vesicular transport protein Rab8. Based on its interaction with Rab8, it is postulated that Rab8ip/GCK may modulate secretion in response to stress stimuli (2). 产品介绍 Human GCK, also known as MAP4K2, GenBank Accession No. NM_004579, full length, with N-terminal GST tag, MW ~125 kDa, expressed in Sf9 insect cells via a baculovirus expression system.
