We report the isolation of Zfp105, the mouse homolog of the human ZNF3
5 zinc finger gene. Zfp105 and ZNF35 are highly conserved at the prote
in and nucleotide level, and Zfp105 maps to a region of mouse Chromoso
me (Chr) 9 that is homologous to the human region containing ZNF35. Zp
f105 is highly expressed in the testis, especially in pachytene sperma
tocytes and round spermatids. The possible role of this gene product i
n maintaining an ordered germ cell differentiation process is discusse
d.
