    Sequence-specific and phosphorylation-dependent proline isomerization: a potential mitotic regulatory mechanism (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-01-07
    Description: Pin1 is an essential and conserved mitotic peptidyl-prolyl isomerase (PPIase) that is distinct from members of two other families of conventional PPIases, cyclophilins and FKBPs (FK-506 binding proteins). In response to their phosphorylation during mitosis, Pin1 binds and regulates members of a highly conserved set of proteins that overlaps with antigens recognized by the mitosis-specific monoclonal antibody MPM-2. Pin1 is here shown to be a phosphorylation-dependent PPIase that specifically recognizes the phosphoserine-proline or phosphothreonine-proline bonds present in mitotic phosphoproteins. Both Pin1 and MPM-2 selected similar phosphorylated serine-proline-containing peptides, providing the basis for the specific interaction between Pin1 and MPM-2 antigens. Pin1 preferentially isomerized proline residues preceded by phosphorylated serine or threonine with up to 1300-fold selectivity compared with unphosphorylated peptides. Pin1 may thus regulate mitotic progression by catalyzing sequence-specific and phosphorylation-dependent proline isomerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yaffe, M B -- Schutkowski, M -- Shen, M -- Zhou, X Z -- Stukenberg, P T -- Rahfeld, J U -- Xu, J -- Kuang, J -- Kirschner, M W -- Fischer, G -- Cantley, L C -- Lu, K P -- GM56203/GM/NIGMS NIH HHS/ -- GM56230/GM/NIGMS NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Dec 12;278(5345):1957-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9395400" target="_blank"〉PubMed〈/a〉

    Recognition of unique carboxyl-terminal motifs by distinct PDZ domains (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-03
    Description: The oriented peptide library technique was used to investigate the peptide-binding specificities of nine PDZ domains. Each PDZ domain selected peptides with hydrophobic residues at the carboxyl terminus. Individual PDZ domains selected unique optimal motifs defined primarily by the carboxyl terminal three to seven residues of the peptides. One family of PDZ domains, including those of the Discs Large protein, selected peptides with the consensus motif Glu-(Ser/Thr)-Xxx-(Val/Ile) (where Xxx represents any amino acid) at the carboxyl terminus. In contrast, another family of PDZ domains, including those of LIN-2, p55, and Tiam-1, selected peptides with hydrophobic or aromatic side chains at the carboxyl terminal three residues. On the basis of crystal structures of the PSD-95-3 PDZ domain, the specificities observed with the peptide library can be rationalized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Songyang, Z -- Fanning, A S -- Fu, C -- Xu, J -- Marfatia, S M -- Chishti, A H -- Crompton, A -- Chan, A C -- Anderson, J M -- Cantley, L C -- CA66263/CA/NCI NIH HHS/ -- DK34989/DK/NIDDK NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 3;275(5296):73-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Beth Israel Hospital, and Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8974395" target="_blank"〉PubMed〈/a〉

    Major susceptibility locus for prostate cancer on chromosome 1 suggested by a genome-wide search (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-11-22
    Description: Despite its high prevalence, very little is known regarding genetic predisposition to prostate cancer. A genome-wide scan performed in 66 high-risk prostate cancer families has provided evidence of linkage to the long arm of chromosome 1 (1q24-25). Analysis of an additional set of 25 North American and Swedish families with markers in this region resulted in significant evidence of linkage in the combined set of 91 families. The data provide strong evidence of a major prostate cancer susceptibility locus on chromosome 1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, J R -- Freije, D -- Carpten, J D -- Gronberg, H -- Xu, J -- Isaacs, S D -- Brownstein, M J -- Bova, G S -- Guo, H -- Bujnovszky, P -- Nusskern, D R -- Damber, J E -- Bergh, A -- Emanuelsson, M -- Kallioniemi, O P -- Walker-Daniels, J -- Bailey-Wilson, J E -- Beaty, T H -- Meyers, D A -- Walsh, P C -- Collins, F S -- Trent, J M -- Isaacs, W B -- CA58236/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 Nov 22;274(5291):1371-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Human Genome Research, National Institutes of Health, Bethesda, MD, USA. jtrent@nchgr.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8910276" target="_blank"〉PubMed〈/a〉
