title: [Preparation and characterization of antisera specific to various polypeptide domains corresponding to the v-ets oncogene of the avian leukemia virus E26].
abstract: We prepared antisera to three distinct portions of the v-ets oncogene of the avian leukemia virus E26. An antiserum directed against the middle v-ets-encoded domain identifies in different chicken cell lines and normal tissues a c-ets-encoded protein of Mr 54,000 (P54c-ets) and three proteins of Mr 60,000 62,000 and 64,000 partially related to P54c-ets. Antisera directed against the aminoterminal v-ets-encoded domain failed to precipitate P54c-ets or P60/P64. Thus, the E26 specific v-ets oncogene displays a complex structure that includes several distinct portions, the genetic origin of which could be different.
