      Carnosine and related β-alanine–containing peptides are believed to be important antioxidants, pH buffers, and neuromodulators. However, their biosynthetic routes and therapeutic potential are still being debated. This ...
    • HAMLET forms annular oligomers when deposited with phoshpolipid monolayers 

      Baumann, Anne; Gjerde, Anja Underhaug; Ying, Ming; Svanborg, Catharina; Holmsen, Holm A.; Glomm, Wilhelm; Martinez, Aurora; Halskau, Øyvind (Peer reviewed; Journal article, 2012-04)
      Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ...
    • HAMLET interacts with lipid membranes and perturbs their structure and integrity 

      Mossberg, Ann-Kristin; Puchades, Maja; Halskau, Øyvind; Baumann, Anne; Lanekoff, Ingela; Chao, Yinxia; Martinez, Aurora; Svanborg, Catharina; Karlsson, Roger (Peer reviewed; Journal article, 2010-01-23)
      Background Cell membrane interactions rely on lipid bilayer constituents and molecules inserted within the membrane, including specific receptors. HAMLET (human α-lactalbumin made lethal to tumor cells) is a tumoricidal ...
    • Membrane Association Landscape of Myelin Basic Protein Portrays Formation of the Myelin Major Dense Line 

      Raasakka, Arne; Ruskamo, Salla; Kowal, Julia; Barker, Robert; Baumann, Anne; Martel, Anne; Tuusa, Jussi; Myllykoski, Matti; Bürck, Jochen; Ulrich, Anne S.; Stahlberg, Henning; Kursula, Petri (Peer reviewed; Journal article, 2017-07-10)
      Compact myelin comprises most of the dry weight of myelin, and its insulative nature is the basis for saltatory conduction of nerve impulses. The major dense line (MDL) is a 3-nm compartment between two cytoplasmic leaflets ...
    • Molecular structure and function of myelin protein P0 in membrane stacking 

      Raasakka, Arne; Ruskamo, Salla; Kowal, Julia; Han, Huijong; Baumann, Anne; Myllykoski, Matti; Fasano, Anna; Rossano, Rocco; Riccio, Paolo; Bürck, Jochen; Ulrich, Anne S.; Stahlberg, Henning; Kursula, Petri (Peer reviewed; Journal article, 2019)
      Compact myelin forms the basis of nerve insulation essential for higher vertebrates. Dozens of myelin membrane bilayers undergo tight stacking, and in the peripheral nervous system, this is partially enabled by myelin ...
    • The N-terminal sequence of tyrosine hydroxylase is a conformationally versatile motif that binds 14-3-3 proteins and membranes 

      Skjevik, Åge Aleksander; Mileni, Mauro; Baumann, Anne; Halskau, Øyvind; Teigen, Knut; Raymond C., Stevens; Martinez, Aurora (Peer reviewed; Journal article, 2014-01-09)
      Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the synthesis of catecholamine neurotransmitters, and a reduction in TH activity is associated with several neurological diseases. Human TH is regulated, among ...
    • The Peripheral Binding of 14-3-3γ to Membranes Involves Isoform-Specific Histidine Residues 

      Bustad, Helene J.; Skjærven, Lars; Ying, Ming; Halskau, Øyvind; Baumann, Anne; Rodriguez-Larrea, David; Costas, Miguel; Underhaug, Jarl; Sanchez-Ruiz, Jose M.; Martinez, Aurora (Peer reviewed; Journal article, 2012-11-26)
      Mammalian 14-3-3 protein scaffolds include seven conserved isoforms that bind numerous phosphorylated protein partners and regulate many cellular processes. Some 14-3-3-isoforms, notably γ, have elevated affinity for ...
    • Stable preparations of tyrosine hydroxylase provide the solution structure of the full-length enzyme 

      Bezem, Maria Teresa; Baumann, Anne; Skjærven, Lars; Meyer, Romain; Kursula, Petri; Martinez, Aurora; Flydal, Marte Innselset (Peer reviewed; Journal article, 2016-07-27)
