NCIt definition : Inactive tyrosine-protein kinase PEAK1 (1746 aa, 193 kDa) is encoded by the human
PEAK1 gene. This protein is involved in the modulation of focal adhesion dynamics.;
NCIt note : The catalytic activity of inactive tyrosine-protein kinase PEAK1 has been a subject
of controversy. In vitro studies found weak tyrosine-protein kinase activity. However,
the crystal structure indicates that the kinase-domain contains a closed nucleotide-binding
cleft and a thermal-shift assay indicates that the protein is devoid of nucleotide
binding activity. (UniProt);
