The AF-4 gene on human chromosome 4q21 is involved in reciprocal translocations to the ALL-1 gene on chromosome 11q23, which are associated with acute lymphoblastic leukaemias. A set of recombinant phage carrying genomic fragments for the coding region and flanking sequences of the AF-4 gene were isolated. Phage inserts were assembled into four contigs with(More)
Chromosomal translocations t(4;11) are based on illegitimate recombinations between the human MLL and AF4 genes, and are associated with high-risk acute leukemias of infants and young children. Here, the question was asked, whether a correlation exists between the location of translocation breakpoints within both genes and the location of S/MARs. In "halo(More)
The complete cDNA coding sequence and derived amino acid sequence of human complement component C3 are presented. The encoded precursor molecule contains a signal peptide of 22 amino acid residues, the beta chain (645 residues), and the alpha chain (992 residues). The two chains are joined by four arginine residues not present in the mature protein. Several(More)
Gemtuzumab ozogamicin (GO, Mylotarg) is a targeted therapeutic agent in which an anti-CD33 antibody is chemically coupled to a highly cytotoxic calicheamicin derivative through a hydrolysable linker. GO has improved the treatment outcome for a subgroup of acute myeloid leukemia (AML) patients, but its use is associated with severe myelosuppression and(More)
The amino acid sequence of a 90-residue segment of human pregnancy zone protein containing its bait region has been determined. Human alpha 2-macroglobulin, human pregnancy zone protein, and rat alpha 1-macroglobulin, alpha 2-macroglobulin, and alpha 1-inhibitor 3 variants 1 and 2 constitute a group of homologous proteins; but the sequences of their bait(More)
Members of the Rab family of small GTPases play important roles in membrane trafficking along the exocytic and endocytic pathways. The Rab11 subfamily consists of two highly conserved members, Rab11a and Rab11b. Rab11a has been localized both to the pericentriolar recycling endosome and to the trans-Golgi network and functions in recycling of transferrin.(More)
The molecular architecture of human complement component C7 was elucidated at several structural levels. The complete primary structure of C7 was derived from the cDNA sequence of clones isolated from a human liver library. C7 is a mosaic protein that consists of 821 amino acids. The amino-terminal two-thirds of C7 has 23-30% homology with complement(More)
Interleukin 6 (IL-6) was established as a transcriptional inducer of the rat alpha 2-macroglobulin gene, a prototype liver acute-phase gene. Maximum induction occurred when the 5' flanking sequences of this gene (position -209 to -43) directed expression from the gene's own TATA box and transcription start site. Removal of the hexanucleotide CTGGGA(More)
The cytoplasmic domain of the receptor for interleukin 10 (IL-10R) contains two box 3 sequence motifs that have been identified in the signal-transducing receptor subunits for IL-6-type cytokines and noted to be required for activating STAT3 and inducing transcription through IL-6-responsive elements. To determine whether the IL-10R has signaling functions(More)
One class of genes coding for the acute-phase proteins (acute-phase genes) is induced by interleukin 6 (IL-6) through the human transcription factor NF-IL-6 and its rat homolog IL-6-DBP/LAP. A second class, represented by the rat alpha 2 macroglobulin gene, utilizes a different IL-6 response element (IL-6-RE) and different DNA-binding proteins interacting(More)
