Differential expression of the zinc finger gene Zfp105 during spermatogenesis.

We report the isolation of Zfp105, the mouse homolog of the human ZNF35 zinc finger gene. Zfp105 and ZNF35 are highly conserved at the protein and nucleotide level, and Zfp105 maps to a region of mouse Chromosome (Chr) 9 that is homologous to the human region containing ZNF35. Zpf105 is highly expressed in the testis, especially in pachytene spermatocytes and round spermatids. The possible role of this gene product in maintaining an ordered germ cell differentiation process is discussed
