Molecular cloning and characterization of a novel splice variant of human ZNF300 gene, which expressed highly in testis.
Zinc finger protein, one of the most important transcription factors, plays an essential role in regulating gene expression. C(2)H(2) type zinc protein with KRAB domain contains two parts, one is C(2)H(2) zinc finger motif which is use to binding to the DNA, while the other is KRAB associated box which mostly performs as a transcription repressor. In this study, we report the cloning and characterization of a novel splice variant of the human ZNF300 gene (ZNF300-B). The ZNF300-B gene cDNA is 2293 bp in length, encoding a putative protein with 619 amino acid residues. ZNF300-B gene is mapped to chromosome 5q32-5q33 with seven exons. Reverse transcription polymerase chain reaction (RT-PCR) analysis showed that ZNF300-B and ZNF-300 were expressed highly in human testis.
