The structural gene for F liver protein (Flp) maps to chromosome 5 of the mouse.
The BXD and AKXL panels of recombinant inbred mouse strains have been typed for the F liver protein alloantigen. The structural gene for F liver protein gene (Flp) is placed on the distal part of chromosome 5, between the known markers Bcd-1 and Gus-s. This excludes the possibility that F liver protein is a major histocompatibility complex molecule, and in turn raises a question about the uniqueness of F and certain other proteins as purgers of self-reactivity among T but not B cells. The typed RI strains have then been used for the immunogenetic studies presented in the succeeding article.

New ideas about self-tolerance and auto-immunity.
Recent advances in our understanding of B cell ontogeny strengthen the theory that self-tolerance is generated principally by clonal deletion. B cells pass through a stage: the "baby B cell", during which they are particularly susceptible to receptor cross-linking. Further evidence of clonal deletion comes from studies on the maintenance of the liver differentiation alloantigen F. In spite of this accumulating evidence room can still be found for the concept of immunological silence: it is a prediction of the dual recognition theory of T cell receptors that differentiation macromolecules which occur only on the surface of Ia negative cells cannot be seen by T helper cells.
