title: Specific proteolytic fragmentation of p60v-src in transformed cell lysates.
abstract: Work involving the transforming protein, p60v-src, of Rous sarcoma virus has resulted in the extensive characterization of its protein structure and associated phosphotransferase activity. However, in many investigations proteolytic fragments (principally p52v-src) of the src protein are actually studied. Here, we emphasize potential problems in the interpretation of experimental results in which the proteolytic fragmentation of p60v-src may be involved and offer several means for the complete prevention of this p60v-src degradation.
