Disease relevance of DNALI1

  • Retrovirus expressing a dominant negative FGFR construct (FGFRdn) and green fluorescent protein (GFP) was injected into the dorsal columns of postnatal day 7 (P7) mice followed by perfusion at P28 [1].
  • Chronic hypoxia was induced by continuously exposing rats (n = 23) to 10% O2 from postnatal day (P) 3 to P28 [2].
  • Mice (BALB/c) were vaccinated with the HIV-1 gp120 envelope glycoprotein (Env(gp120)) alone or fused to multiple copies of the murine C3d or a twenty-eight amino-acid peptide (P28) containing a minimum CR2 binding domain [3].

High impact information on DNALI1

  • Binding studies with these two fragments showed that only the Mr 8,600 fragment bound to both H and alpha alpha H. Several synthetic peptides (A58, 1192-1249; P28, 1187-1214; P16, 1194-1209; P14, 1201-1214; B17, 1206-1222; J28, 1222-1249; and J16, 1234-1249) were synthesized according to the primary sequence of the Mr 8,600 fragment [4].
  • Using somatic cell and radiation hybrid panels, the hp28 gene was mapped to human chromosome 1p35 [5].
  • We subjected male Sprague-Dawley rats at postnatal day (P)7, P14, P21, and P28 to either a saline or lipopolysaccharide (LPS) injection and examined them in adulthood for differences in responses to a further LPS injection [6].
  • In contrast, a strong signal was apparent in the anterodorsal nucleus, which projects to limbic areas, and this persisted at P28 [7].
  • To determine their sources, we injected sodium selenite into the barrel cortex of two adult rats and 32 pups, from P5 to P28 [7].

Biological context of DNALI1

  • To identify putative Dnali1 interacting polypeptides, a yeast two-hybrid approach was performed using a murine testicular cDNA library [8].
  • The Dnali1 gene is localized on chromosome 4 and consists of six exons [8].
  • The peptide, synthesized chemically according to the amino acid sequence of the 3-kDa peptide (designated P28), showed CETP inhibitory activity both in vitro and in vivo ICho et al [9].

Anatomical context of DNALI1

  • By P28 the distribution of all proteins is similar, occupying the entire chiasm, optic tracts, and prechiasmatic portion of the optic nerves [10].
  • Staining of neuronal somata in the dorsal cochlear nucleus molecular layer and fusiform cell layer, the posteroventral cochlear nucleus octopus cell area, and the anteroventral cochlear nucleus increased from P7 to P28 [11].
  • It is predominantly expressed within the testis but at a lower level Dnali1 transcripts were also observed in different murine tissues, which exhibit cilia [8].
  • Dnali1 is strongly expressed in spermatids but was also detected in spermatocytes [8].
  • Moreover, the Dnali1 protein was localized in cilia of the trachea as well as in flagella of mature sperm supporting its function as an axonemal dynein [8].

Associations of DNALI1 with chemical compounds

  • Methods: Pregnant TSC2+/- females were injected once a day with hydroquinone (HQ), and offspring were killed at postnatal day P14 or P28 [12].
  • P28 was found to be located in HDL fractions of hog plasma and showed the same electromobility as that visualized by PAGE on 7% polyacrylamide gel under nondenaturing conditions [9].
  • The P22 possesses homology with members of the Kunitz family of trypsin inhibitor; the P28.5 is homologous to ascorbate peroxidase of several plant species while P28 did not exhibit significant homology with sequences archived in available databases [13].

Physical interactions of DNALI1


Analytical, diagnostic and therapeutic context of DNALI1

  • Northern blot analysis reveals two hp28 gene transcripts, 0.9 and 2.5 kb, in many tissues [5].
  • No IRBP was detected by immunocytochemistry in rats at P28 [14].
  • Western blot analysis revealed that P28 was associated only with human and hog HDL among several lipoproteins purified from human, hog, and rabbit [9].
  • The fusion of C3d or P28 to Env(gp120) elicited higher-titer anti-Env specific antibody, enhanced avidity maturation of the elicited antibody, and elicited higher numbers of IFN-gamma and IL-4 secreting cells compared to Env(gp120) immunizations [3].
