title: Female expression of the H-2-linked sex-limited protein (Slp) due to non-H-2 genes.
abstract: Female mice of 15 inbred strains in which males express the H-2-linked sex-limited protein (Slp) were tested for the production of this protein. Four inbred strains (FM, LG/J, NZB, PL/J) were found in which females produce Slp in the absence of hormonal manipulation. Crosses have been made between strains FM, NZB, or PL/J and several Slp-negative strains. Slp-typing of the F1, F2, and backcross progeny, as well as of a number of recombinant inbred strains, indicates that production of Slp by normal females of these strains depends upon the concurrent presence of an Slp-positive, H-2-linked allele and of permissive alleles of one or two non-H-2 autosomal genes. Complementation studies with two of the strains (FM and PL) indicate that an identical genetic mechanism mediates expression of Slp in females of these two strains. FM-derived animals carrying the testicular feminization mutation (tfm) also express Slp, as do castrated NZB mice, indicating that Slp expression in these instances is not dependent upon testosterone as it is in other inbred strains. It is concluded from these results that genes distinct from the putative structural gene for Slp influence the sex-limitation of its expression.
