Synonym Discussion of interrogate. Proto-oncogene tyrosine-protein kinase Src, also known as proto-oncogene c-Src, or simply c-Src (cellular Src; pronounced "sarc", as it is short for sarcoma), is a non-receptor tyrosine kinase protein that in humans is encoded by the SRC gene.It belongs to a family of Src family kinases and is similar to the v-Src (viral Src) gene of Rous sarcoma virus.
