Product Description

The kit provides a means of performing enzymatic assays with active human ABL1 kinase. It includes active ABL1 kinase (supplied as a GST fusion protein), a biotinylated substrate peptide and a phospho-tyorsine monoclonal antibody for detection of the phosphorylated form of the substrate peptide.

Molecular Formula:

Peptide Substrate, Biotin-Signal Transduction Protein (Tyr160): 1830 Daltons, GST-ABL1 Kinase domain: 74,140 Daltons

Peptide Core Sequence:


The c-Abl proto-oncogene encodes a nonreceptor protein tyrosine kinase that is ubiquitously expressed and highly conserved in metazoan evolution. c-Abl protein is distributed in both the nucleus and the cytoplasm of cells. It is implicated in regulating cell proliferation, differentiation, apoptosis, cell adhesion, and stress responses (1-3). c-Abl kinase activity is increased in vivo by diverse physiological stimuli including integrin activation; PDGF stimulation; and binding to c-Jun, Nck, and RFX1 (2,4). The in vivo mechanism for regulation of c-Abl kinase activity is not completely understood. Tyr245 is located in the linker region between the SH2 and catalytic domains. This positioning is conserved among Abl family members. Phosphorylation at Tyr245 is involved in the activation of c-Abl kinase (5). In addition, phosphorylation at Tyr412, which is located in the kinase activation loop of c-Abl, is required for kinase activity (6).
