ZC3H7A (Zinc Finger CCCH-Type Containing 7A, also known as ZC3H7; HSPC055; ZC3HDC7), a member of CCCH gene family, is located on human chromosome 16p13.13. ZC3H7A is associated with some diseases, including Endometrial Stromal Tumor and Endometrial Stromal Sarcoma. An important paralog of this gene is ZC3H7B. The CCCH zinc finger motif has been found in proteins from organisms ranging from man to yeast. The CCCH proteins are a large family of zinc finger containing C3H-type motifs and much evidences proved that they may be RNA-binding proteins functioning in RNA processing. In mouse, tristetraprolin, a protein containing two CCCH zinc fingers, binds directly to AU-rich elements within the 3'-untranslated region of target transcripts to facilitate mRNA degradation. Zfp36l2, like its better-known relative TTP, is a mRNA-binding and destabilizing protein, functions in the physiological control of female fertility at the level of early embryonic development. The PIE-1 is an essential regulator of Caenorhabditis elegans germ cell fate that segregates with the germ lineage by inhibition of transcription or activation of protein expression from maternal RNAs.
