NCIt definition : Adapter molecule crk (304 aa, 34 kDa) is encoded by the human CRK gene. This protein
is involved in the modulation of signal transduction.;
NCIt note : Adapter molecule crk is expressed as two isoforms (Crk-I and Crk-II) that are generated
by alternative splicing. The Crk-I form is missing the second SH3 domain and has higher
transforming activity. (UniProt);
