Purified (~70-90%). PEAK1 or Pseudopodium-enriched atypical kinase 1, is a protein tyrosine kinase which belongs to NKF3 kinase family and regulates the cytoskeleton and has been shown to be involved in cancer progression. PEAK1 promotes anchorage-independent growth in the MDA-MB-435 human cancer cell line and promotes tumor progression of XPA-1 human pancreatic cancer cells when transplanted into the pancreas of nude mice. PEAK1 is highly expressed in spleen, followed by heart, ovary, brain, lung, kidney, and fetal brain. Source: Recombinant protein corresponding to human PEAK1, fused to GST-Tag at N-terminal expressed in Insect cells. Molecular Weight: ~100kD Specific Activity: 6nmol/min/mg as per activity assay protocol. Endotoxin: <1EU/ug (LAL)
