    Caspase-3-generated fragment of gelsolin: effector of morphological change in apoptosis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-10-10
    Description: The caspase-3 (CPP32, apopain, YAMA) family of cysteinyl proteases has been implicated as key mediators of apoptosis in mammalian cells. Gelsolin was identified as a substrate for caspase-3 by screening the translation products of small complementary DNA pools for sensitivity to cleavage by caspase-3. Gelsolin was cleaved in vivo in a caspase-dependent manner in cells stimulated by Fas. Caspase-cleaved gelsolin severed actin filaments in vitro in a Ca2+-independent manner. Expression of the gelsolin cleavage product in multiple cell types caused the cells to round up, detach from the plate, and undergo nuclear fragmentation. Neutrophils isolated from mice lacking gelsolin had delayed onset of both blebbing and DNA fragmentation, following apoptosis induction, compared with wild-type neutrophils. Thus, cleaved gelsolin may be one physiological effector of morphologic change during apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kothakota, S -- Azuma, T -- Reinhard, C -- Klippel, A -- Tang, J -- Chu, K -- McGarry, T J -- Kirschner, M W -- Koths, K -- Kwiatkowski, D J -- Williams, L T -- P01 HL48743/HL/NHLBI NIH HHS/ -- R01 HL54188/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 10;278(5336):294-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chiron Corporation, Emeryville, CA 94608, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9323209" target="_blank"〉PubMed〈/a〉

    Molecular cloning of two types of GAP complementary DNA from human placenta (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-23
    Description: The ras p21 GTPase-activating protein (GAP) was purified from human placental tissue. Internal amino acid sequence was obtained from this 120,000-dalton protein and, by means of this sequence, two types of complementary DNA clones were isolated and characterized. One type encoded GAP with a predicted molecular mass of 116,000 daltons and 96% identity with bovine GAP. The messenger RNA of this GAP was detected in human lung, brain, liver, leukocytes, and placenta. The second type appeared to be generated by a differential splicing mechanism and encoded a novel form of GAP with a predicted molecular mass of 100,400 daltons. This protein lacks the hydrophobic amino terminus characteristic of the larger species, but retains GAP activity. The messenger RNA of this type was abundantly expressed in placenta and in several human cell lines, but not in adult tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trahey, M -- Wong, G -- Halenbeck, R -- Rubinfeld, B -- Martin, G A -- Ladner, M -- Long, C M -- Crosier, W J -- Watt, K -- Koths, K -- New York, N.Y. -- Science. 1988 Dec 23;242(4886):1697-700.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Cetus Corp., Emeryville, CA 94608.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3201259" target="_blank"〉PubMed〈/a〉

    Three-dimensional structure of dimeric human recombinant macrophage colony-stimulating factor (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-20
    Description: Macrophage colony-stimulating factor (M-CSF) triggers the development of cells of the monocyte-macrophage lineage and has a variety of stimulatory effects on mature cells of this class. The biologically active form of M-CSF is a disulfide-linked dimer that activates an intrinsic tyrosine kinase activity on the M-CSF receptor by inducing dimerization of the receptor molecules. The structure of a recombinant human M-CSF dimer, determined at 2.5 angstroms by x-ray crystallography, contains two bundles of four alpha helices laid end-to-end, with an interchain disulfide bond. Individual monomers of M-CSF show a close structural similarity to the cytokines granulocyte-macrophage colony-stimulating factor and human growth hormone. Both of these cytokines are monomeric in their active form, and their specific receptors lack intrinsic tyrosine kinase activity. The similarity of these structures suggests that the receptor binding determinants for all three cytokines may be similar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pandit, J -- Bohm, A -- Jancarik, J -- Halenbeck, R -- Koths, K -- Kim, S H -- New York, N.Y. -- Science. 1992 Nov 20;258(5086):1358-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology Division, Lawrence Berkeley Laboratory, Berkeley, CA 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1455231" target="_blank"〉PubMed〈/a〉

    Biological activity of recombinant human interleukin-2 produced in Escherichia coli (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-03-30
    Description: The gene for interleukin-2 was isolated from the Jurkat cell line and from normal peripheral blood lymphocytes and, when inserted in Escherichia coli, was expressed at high concentrations. This interleukin-2 was purified to apparent homogeneity and tested for biological activity in a variety of assays in vitro and in vivo. The recombinant lymphokine supports the growth of murine and human interleukin-2 dependent cell lines, enhances the generation of murine and human cytolytic cells in vitro, and generates lymphokine activated killer cells from murine and human lymphocytes. It has a serum half-life of 2 to 3 minutes in the mouse and significantly enhances the generation of cytolytic cells in vivo after alloimmunization. No functional differences between native and the recombinant interleukin-2 molecules have been detected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, S A -- Grimm, E A -- McGrogan, M -- Doyle, M -- Kawasaki, E -- Koths, K -- Mark, D F -- New York, N.Y. -- Science. 1984 Mar 30;223(4643):1412-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6367046" target="_blank"〉PubMed〈/a〉

    Notes: The single gene for human macrophage colony-stimulating factor (M-CSF, or CSF-1) generates multiple mRNA species that diverge within the coding region. We have characterized translation products of these mRNA species from native and recombinant sources. Immunoblots of reduced native M-CSF indicate that multiple glycosylated species ranging from 25 kd to 200 kd are secreted by human monocytes and cell lines. In contrast, CV-1 cells expressing a short M-CSF clone secrete only 24 kd recombinant M-CSF. Synthetic peptide antibodies were developed to distinguish between secreted recombinant M-CSF from long and short mRNA splicing variants. Immunoblot analysis indicates that alternative mRNA splicing generates some M-CSF protein heterogeneity. Most secreted MIA PaCa-2 M-CSF reacts with long-clone-specific antibody. Lectin affinity chromatography shows that variable glycosylation contributes significantly to MIA PaCa-2 M-CSF size heterogeneity. In addition, cell lysates also contain larger M-CSF species that apparently undergo proteolytic processing before secretion. The data indicate that M-CSF protein heterogeneity results from both pre- and post-translational processing.
