If you are looking for the Raf1 DNA sequence you can find it in the database e,g, NCBI and Ensemble.

I hope I understand what you`re looking for.

Thank you Gusai Eltayeb for your information. What I am finding is Ras-binding domain of Raf1 in mouse. In some papers, this domain is 55-131 codon, but it is in human. 

This alignment of human and mouse CRAF between amino acids 55-131 shows you that they are virtually identical. ie. the same residues in mouse encode the Ras binding domain of CRAF.

Thank you Ian A Prior very much.
