Biological Information

Background Information:

Involved in negative regulation of cell growth. Has tumor suppressor properties. Plays a negative regulatory role in the Ras-MAPK pathway. May function in signaling pathways utilized broadly during fetal development and more selectively in adult tissues and in cells of the lymphohematopoietic system. Could specifically be involved in phospholipid signal transduction.

Testing Information

Procedure Summary:

TNK1 (h) is incubated with 25 mM Tris pH 7.5, 0.2 mM EGTA, 0.5 mM sodium orthovanadate, 0.5 mM sodium βglycerophosphate, 0.01% Triton X-100, 1% Glycerol, 1 mM DTT, 0.33 mg/mL myelin basic protein, 10 mM Magnesium acetate and [γ-33P]-ATP (Specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ATP mix. After incubation for 120 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid solution to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in ethanol prior to drying and scintillation counting.

Substrate:

0.33 mg/mL myelin basic protein
