The structural gene for F liver protein (Flp) maps to chromosome 5 of the mouse

Area of Science:

• Immunogenetics
• Mouse genetics
• Molecular biology

Background:

• The F liver protein alloantigen was analyzed in recombinant inbred mouse strains.
• Previous understanding of F liver protein's genetic location and function was limited.

Purpose of the Study:

• To determine the chromosomal location of the structural gene for F liver protein (Flp).
• To investigate the implications of Flp's location on its role in immune responses.

Main Methods:

• Typing of BXD and AKXL recombinant inbred mouse panels for F liver protein alloantigen.
• Genetic mapping of the Flp gene using known chromosomal markers.

Main Results:

• The Flp gene was localized to the distal part of mouse chromosome 5.
• The location of Flp excludes it from being a major histocompatibility complex molecule.

Conclusions:

• The F liver protein is not part of the major histocompatibility complex.
• The study raises questions about the specific role of F liver protein in T cell self-reactivity compared to B cells.
