| TAK1

Mitogen-activated protein kinase kinase kinase 7 (MAP3K7), also known as TAK1, is an enzyme that is encoded by the MAP3K7 gene. TAK1 is an evolutionarily conserved kinase in the MAP3 K family and clusters with the tyrosine-like and sterile kinase families. The protein structure of TAK1 contains an N (residues 1–104)- and C (residues 111–303)-terminus connected through the hinge region (Met 104-Ser 111). The ATP binding pocket is located in the hinge region of the kinase. Additionally, TAK1 has a catalytic lysine (Lys63) in the active site. Crystal structure of TAK1-ATP have shown that ATP forms two hydrogen bonds with residues Ala 107 and Glu 105.

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Mouse TAK1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-101	96
Cell Lysates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse TAK1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)

	Average (%)	91	96
1 : 4	Range (%)	89-102	105-115
	Average (%)	94	108
