42. We have also identified putative X-linked human orthologs of the other three novel
X-linked mouse genes: Tktl1, Tex16, and Pramel3. The human TKTL1 gene was
previously discovered and shown to be expressed in many somatic tissues [J. F. Coy
et al., Genomics 32, 309 (1996)]; we found that the gene is abundantly transcribed in
testes (not shown). We identified human X-linked sequences (Genbank Z95126)
homologous to mouse Tex16 but observed no expression (as judged by RT-PCR) in
any of the eight human tissues listed in Fig. 3; the human ortholog may be a
pseudogene. We identified human X-linked sequences (Genbank Z70226)
homologous to mousePramel3 but have not characterized the human gene's
expression or cDNA sequence. The search for human orthologs of the remaining
seven novel autosomal mouse genes (Pramel1, Tex17, Rnh2, Tex18, Piwil2, Tex20,
Tex19) is complicated by the existence of multiple related sequences in the human
genome and/or the inavailability of corresponding human genomic sequence. .

55. Mouse Rnf17 appears to encode a protein of 626 residues. A mouse cDNA sequence
corresponding to the 5' portion of Rnf17 was reported recently; it appeared to encode
a protein of 316 residues [X. Y. Yin, K. Gupta, W. P. Han, E. S. Levitan, E. V.
Prochownik, Oncogene 18, 6621 (1999)]. The discrepancy may be the result of
alternative splicing or sequencing errors near the 3' end of the previously reported
cDNA sequence (compare GenBank AF190166 [1098 nucleotides; 951 nucleotide
open reading frame] with GenBank AF285585 [2094 nucleotides; 1881 nucleotide
open reading frame]). Yin and colleagues demonstrated that the portion of the protein
encoded by their partial cDNA interacted with mad proteins in vitro. In the case of
human RNF17, alternative splicing appears to generate two protein isoforms. .
