However , there were some properties of Rak that are distinct from Src - like kinases : ( a ) expression of Rak was predominantly in epithelial - derived cell lines and tissues , especially normal liver and kidney , and cell lines of breast and colon origin ; ( b ) Rak does not harbor the NH2 - terminal glycine essential for myristylation and membrane localization ; and ( c ) Rak possesses a putative bipartite nuclear localization signal in the SH2 domain , and subcellular fractionation studies revealed that p54rak resides predominantly in the nucleus .
