Location of the gene for Theta antigen in the mouse.

Theta (determined by the Thy-1 locus) is a cell-surface antigen found on mouse thymus-derived lymphocytes and in the brain. The expression of theta is controlled by an autosomal gene with two known codominant alleles: Thy-1/sup a/ and Thy-1/sup b/. The purpose of the present study was to define the position of Thy-1 in linkage group II, which has now been identified as chromosome 9. Our experimental design was to measure the recombination between Thy-1 and Trf, the gene controlling an iron-binding serum protein, transferrin. In addition, we followed the segregation at the H-14 locus, which has not previously been assigned to any linkage group. This locus, also known as Ea-2, determines a red-blood cell antigen.
