Description :Rabbit Polyclonal Antibody

Species :

Tag :

Expression System:

Sequence :

Specificity :Recognizes the QIK protein

Cited Applications :WB, ELISA

Cross Reactivity :Human, Mouse and Rat

Host / Isotype / Clone# :Rabbit, IgG

Immunogen :QIK antibody was raised against a 16 amino acid synthetic peptide near the center of human QIK

Purification :Affinity chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data :Western blot analysis of QIK in SW480 cell lysate with QIK antibody at 1 ug/ml.

Scientific Background :QIK is a serine/threonine protein kinase that contains an N-terminal kinase domain, a central domain with ubiquitin-associate motif, and a C-terminal PKA phosphorylation site. QIK can phosphorylate IRS1 and overexpression of QIK in adipocyte elevates the phosphorylation of IRS1 (1). The QIK-mediated phosphorylation of IRS1 may modulate the efficiency of insulin signal transduction and could be responsible for insulin resistance associated with diabetes (1). Insulin disrupts TORC2 activity by induction of QIK which then stimulates the phosphorylation and cytoplasmic translocation of TORC2. Phosphorylated TORC2 is subsequently degraded by the 26S proteasome (2).
