Description

  Human NP220 (hNP220) is a novel DNA-binding nuclear protein, which has an arginine/serine-rich motif and polypyrimidine tract-binding motif, and NP220s and matrin 3 are thought to form a novel family of nuclear proteins. We have determined a chromosomal localization of the cDNA encoding human NP220 to 2p13.1-p13.2 by using fluorescence in situ hybridization. Human matrin 3 cDNA was mapped to chromosomes 1p13.1-p21.1 and 5q31.3, demonstrating that these novel nuclear proteins with similar functions are on different chromosomes.<br>
