Haptoglobin, haptoglobin,, HP1, HP2
This gene encodes a preproprotein, which is processed to yield both alpha and beta chains, which subsequently combine as a tetramer to produce haptoglobin. Haptoglobin functions to bind free plasma hemoglobin, which allows degradative enzymes to gain access to the hemoglobin, while at the same time preventing loss of iron through the kidneys and protecting the kidneys from damage by hemoglobin. Mutations in this gene and/or its regulatory regions cause ahaptoglobinemia or hypohaptoglobinemia. This gene has also been linked to diabetic nephropathy, the incidence of coronary artery disease in type 1 diabetes, Crohn's disease, inflammatory disease behavior, primary sclerosing cholangitis, susceptibility to idiopathic Parkinson's disease, and a reduced incidence of Plasmodium falciparum malaria. A similar duplicated gene is located next to this gene on chromosome 16. Multiple transcript variants encoding different isoforms have been found for this gene.

Feasibility of Affibody Molecule-Based PNA-Mediated Radionuclide Pretargeting of Malignant Tumors.
Karlström et al., Uppsala, Sweden. In Theranostics, Dec 2015
To test this hypothesis, we designed an Affibody-PNA chimera ZHER2:342-SR-HP1 containing a 15-mer HP1 PNA recognition tag and a complementary HP2 hybridization probe permitting labeling with both (125)I and (111)In.
A role for Separase in telomere protection.
Cenci et al., Roma, Italy. In Nat Commun, Dec 2015
We demonstrate that Separase binds terminin proteins and HP1, and that it is enriched at telomeres.
Patching Broken DNA: Nucleosome Dynamics and the Repair of DNA Breaks.
Price et al., Boston, United States. In J Mol Biol, Dec 2015
DSBs promote rapid accumulation of repressive complexes, including HP1, the NuRD complex, H2A.Z and histone methyltransferases at the DSB.
The making of a Barr body: the mosaic of factors that eXIST on the mammalian inactive X chromosome.
Brown et al., Vancouver, Canada. In Biochem Cell Biol, Jul 2015
During XCI, at least two distinct types of heterochromatin are established, and in this review we discuss the enrichment of facultative heterochromatin marks such as H3K27me3, H2AK119ub, and macroH2A as well as pericentric heterochromatin marks such as HP1, H3K9me3, and H4K20me3.
The alternative role of DNA methylation in splicing regulation.
Ast et al., Tel Aviv-Yafo, Israel. In Trends Genet, May 2015
The first involves modulation of the elongation rate of RNA polymerase II (Pol II) by CCCTC-binding factor (CTCF) and methyl-CpG binding protein 2 (MeCP2); the second involves the formation of a protein bridge by heterochromatin protein 1 (HP1) that recruits splicing factors onto transcribed alternative exons.
The telomere bouquet regulates meiotic centromere assembly.
Cooper et al., Bethesda, United States. In Nat Cell Biol, Apr 2015
Kinetochore proteins and the centromeric histone H3 variant Cnp1 fail to localize to those centromeres that exhibit spindle attachment defects in the bouquet's absence.
