Abstract

Several genes are found on both the human X and Y chromosomes in regions that do not recombine during male meiosis. In each case, nucleotide sequence analysis suggests that these X-Y gene pairs encode similar but nonidentical proteins. Here we show that the human Y- and X-encoded ribosomal proteins, RPS4Y and RPS4X, are interchangeable and provide an essential function: either protein rescued a mutant hamster cell line that was otherwise incapable of growth at modestly elevated temperatures. These findings are consistent with the hypothesis that RPS4 deficiency has a role in Turner syndrome, a complex human phenotype associated with monosomy X.
