ROR1 protein is an important member of the Tyr protein kinase family in the protein kinase superfamily and plays a key role as a tyrosine kinase in cell signaling and regulation. Its classification emphasizes its importance in phosphorylation events and shares conserved features with related kinases. ROR1 Protein, Rat (HEK293, His) is the recombinant rat-derived ROR1 protein, expressed by HEK293 , with C-10*His labeled tag.
