We have identified a novel protein, BAP1, which binds to the RING finger domain of the Breast/Ovarian Cancer Susceptibility Gene product, BRCA1. BAP1 is a nuclear-localized, ubiquitin carboxy-terminal hydrolase, suggesting that deubiquitinating enzymes may play a role in BRCA1 function. BAP1 binds to the wild-type BRCA1-RING finger, but not to germline(More)
The Krüppel-associated box (KRAB) is a highly conserved, 75-aa region containing two predicted amphipathic alpha-helices. The KRAB domain is present in the amino-terminal regions of more than one-third of all Krüppel-class Cys2His2 zinc finger proteins and is conserved from yeast to man; however, its function is unknown. Here it is shown that the KRAB(More)
The nuclear receptor protein superfamily is a large group of transcription factors involved in many aspects of animal development, tissue differentiation, and homeostasis in the higher eukaryotes. A subfamily of receptors, ERRalpha and beta (estrogen receptor-related receptor alpha and beta), closely related to the ER, were among the first orphan nuclear(More)
We have isolated and chromosomally fine-mapped 16 novel genes belonging to the human zinc finger Krüppel family (ZNF131-140, 142, 143, 148, 151, 154, and 155), including 1 of the GLI type (ZNF143) and 3 containing a KRAB (Krüppel-associated box) segment (ZNF133, 136, and 140). Based on their map position, several of these ZNF genes are putative candidate(More)
We report the characterization of three novel members of the KRAB-domain containing C2-H2 zinc finger family (ZNF133, 136 and 140). KRAB (Krüppel-associated box) is an evolutionarily conserved protein domain found N-terminally with respect to the zinc finger repeats that encodes the DNA binding domain. ZNF133 and ZNF140 have both the KRAB A- and KRAB(More)
The Wilms tumor suppressor protein, WT1, is a transcription factor capable of activating or repressing transcription of various cellular genes. The mechanisms involved in regulating the transcriptional activities of WT1 are beginning to be unraveled. It appears that physical interactions of other cellular proteins (p53 and par-4) with WT1 can modulate the(More)
The human elongation factor 1alpha gene family consists of at least 2 actively transcribed genes, EEF1A and EEF1A2, and more than 18 homologous loci. EEF1A2 is expressed in a tissue-specific manner, whereas EEF1A is expressed ubiquitously, and both of them can function in translation. An EEF1A cDNA probe has previously been shown to cross-hybridize with(More)
Chromosomal aneusomy is a major cause of reproductive wastage and congenital malformations in man. Zinc finger encoding genes would be good candidates for being involved in the multiple developmental defects associated with chromosomal aneusomy--by virtue of their role as transcriptional regulators, their abundance in the genome and their known association(More)
Expression of the human low-affinity Fc receptors for IgG (human Fc gamma RII) is differentially regulated. We report here the characterization of the promoter structure of the human Fc gamma RIIB gene and the isolation of the promoter region-binding proteins by a yeast one-hybrid assay. The minimal 154-bp region upstream from the transcription start site(More)
