    Description: A hallmark of mitosis is the appearance of high levels of histone phosphorylation, yet the roles of these modifications remain largely unknown. Here, we demonstrate that histone H3 phosphorylated at threonine 3 is directly recognized by an evolutionarily conserved binding pocket in the BIR domain of Survivin, which is a member of the chromosomal passenger complex (CPC). This binding mediates recruitment of the CPC to chromosomes and the resulting activation of its kinase subunit Aurora B. Consistently, modulation of the kinase activity of Haspin, which phosphorylates H3T3, leads to defects in the Aurora B-dependent processes of spindle assembly and inhibition of nuclear reformation. These findings establish a direct cellular role for mitotic histone H3T3 phosphorylation, which is read and translated by the CPC to ensure accurate cell division.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, Alexander E -- Ghenoiu, Cristina -- Xue, John Z -- Zierhut, Christian -- Kimura, Hiroshi -- Funabiki, Hironori -- GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249-01/GM/NIGMS NIH HHS/ -- R01 GM075249-02/GM/NIGMS NIH HHS/ -- R01 GM075249-03/GM/NIGMS NIH HHS/ -- R01 GM075249-04/GM/NIGMS NIH HHS/ -- R01 GM075249-05/GM/NIGMS NIH HHS/ -- R01 GM075249-05S1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):235-9. doi: 10.1126/science.1189505.

    Description: Cytokines are inflammatory mediators important in responding to pathogens and other foreign challenges. Interleukin-4 (IL-4) and IL-13 are two cytokines produced by T helper type 2 cells, mast cells, and basophils. In addition to their physiological roles, these cytokines are also implicated in pathological conditions such as asthma and allergy. IL-4 can stimulate two receptors, type I and type II, whereas IL-13 signaling is mediated only by the type II receptor (see the STKE Connections Maps). These cytokines activate the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling cascades, which may contribute to allergic responses. In addition, stimulation of the phosphatidylinositol 3-kinase (PI3K) pathway through recruitment of members of the insulin receptor substrate family may contribute to survival and proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly-Welch, Ann E -- Hanson, Erica M -- Boothby, Mark R -- Keegan, Achsah D -- AI38985/AI/NIAID NIH HHS/ -- AI45662/AI/NIAID NIH HHS/ -- AI49460/AI/NIAID NIH HHS/ -- GM42550/GM/NIGMS NIH HHS/ -- HL61752/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2003 Jun 6;300(5625):1527-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Holland Laboratory, American Red Cross, Rockville, MD 20855, and the Institute for Biomedical Sciences, George Washington Medical Center, Washington, DC 20037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12791978" target="_blank"〉PubMed〈/a〉
