  • Divalent metal transporter 1 (DMT1) is generally considered to be the major transmembrane protein responsible for the uptake of a variety of divalent cations. (cdc.gov)
  • This new approach has been shown to preserve mobility and enzymatic activity of transmembrane proteins in the resulting nSLB. (lu.se)
  • At both the mRNA and protein levels, most AKR isoforms were highly expressed in the upper regions of the intestine, namely, the duodenum and jejunum, and then declined toward the rectum. (aspetjournals.org)
  • The mRNA level of AKR1B10 was highest, followed by AKR7A3 and CBR1, each accounting for more than 10% of the sum of all AKR and SDR levels in the small intestine. (aspetjournals.org)
  • HLA- em DRB1 /em genotypes, high disease activity, high disability scores, and high levels of acute phase proteins [2]. (exposed-skin-care.net)
  • One previously reported candidate (syb), a Drosophila homolog of the vamp or synaptobrevin proteins, has been shown to be expressed at very low levels in neurons and is most abundant in the gut. (jneurosci.org)
  • Dysfibrinogenemia is a condition characterized by abnormally functioning fibrinogen, although the protein is present at normal levels. (medlineplus.gov)
  • Hypodysfibrinogenemia is a condition characterized by low levels of abnormally functioning fibrinogen protein in the blood. (medlineplus.gov)
  • Strong evidence supports a pathogenic role of altered microtubule-associated protein tau (MAPT) as the shared molecular mechanism of disease amongst the collectively termed tauopathies. (biomedcentral.com)
  • The AF-1 plays an important role in the interaction of the receptor with molecules necessary for the initiation of transcription, such as coactivators, chromatin modulators, and basal transcription factors, including RNA polymerase II, TATA-binding protein (TBP), and a host of TBP-associated proteins (TAFIIs).
