背景介绍 PKCβI is a member of the PKC family (phospholipid-dependent serine/threonine kinase) and is highly related to PKCβ II. Unlike the mature PKCβII mRNA and protein, which rapidly increase following acute insulin treatment, the PKCβI mRNA and protein levels remain unchanged (1). The stable overexpression of PKCβII, but not PKCβI, leads to insulin-stimulated glucose uptake into cells. Upon stimulation of B lymphocytes and mast cells, Syk regulates Btk, and Btk selectively regulates enzymatic activity of PKCβI. Specific regulation of PKCβI by Btk is consistent with the selective association of Btk with PKCβI (2). 产品介绍 Recombinant human PKCβI (PKCbeta1), full length, with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
