Ubiquitous nonimmunoglobulin p-azobenzenearsonate-binding molecules from lymphoid cells.
A ubiquitous nonimmunoglobulin molecule that binds p-azobenzenearsonate (ABA) has been detected in the cytoplasm of several murine cell lines, including T cell hybridomas as well as in normal liver and spleen. Similar to many recently described antigen-specific T cell factors, this ABA-binding protein has a 62,000 mol wt, and, when analyzed by direct binding, the molecule reacts with several different rabbit anti-idiotypic antisera specific to the ABA system. The presence of this antigen-specific, "idiotype positive" molecule in many different cells indicates that it is not an important immunoregulatory molecule.
