Disease relevance of TSPAN7

 

Psychiatry related information on TSPAN7

  • Dopamine (DA) is produced in numerous brain areas and influences a wide variety of social behaviors, but very few data are available to establish the socially-relevant response properties of most DA populations, which comprise eight cell groups numbered A8-A15 [5].
 

High impact information on TSPAN7

 

Chemical compound and disease context of TSPAN7

  • The highly conserved A15-G16 dipeptide may play a role in the function of fusion domain of HIV-1 envelope glycoprotein [7].
 

Biological context of TSPAN7

  • The cDNA was also essentially identical to A15, which was isolated from another T-ALL cell line, HPB-ALL, by differential hybridization with normal peripheral blood lymphocytes, and to CCG-B7, which was isolated from a brain cDNA library using CCG repeat as a probe [2].
  • The A15 gene codes for a protein of 244 amino acids which contains four potential transmembrane domains and four possible N-linked glycosylation sites [8].
  • Our findings provide a novel insight into the malignant phenotype of DSRCT, suggesting that TALLA-1 is a useful marker for diagnosis and a potential target for the therapy of DSRCT [9].
  • The mouse S100A15 ortholog parallels genomic organization, structure, gene expression, and protein-processing pattern of the human S100A7/A15 subfamily during epidermal maturation [10].
  • A cosmid library has been constructed with DNA isolated from a mouse/human hybrid cell line designated A15, which was previously characterized and shown to retain chromosome 15 as the only human material [11].
 

Anatomical context of TSPAN7

  • The A15 is expressed in immature human T cells and in the human brain [1].
  • Total FMLP-ase and carboxypeptidase activities were similar in controls and UC patients but were substantially reduced in CD, especially in the terminal ileum (controls 493 +/- 146 and 116 +/- 73 nmol/100 micrograms protein per h, respectively and CD 231 +/- 96 and 41 +/- 36 nmol/100 micrograms protein per h, respectively (P = 0.0018 and 0.015) [12].
  • A15-year-old girl who developed traumatic iliacus hematoma and complete paralysis of the quadriceps muscle is reported [13].
 

Associations of TSPAN7 with chemical compounds

  • The primary structure of the peptide was established as: [formula: see text] This amino acid sequence contains several unusual substitutions (Gln-->Lys at A5, His-->Leu at A8, Gln-->Glu at A15, and Gly -->Ala at B20) that are not present in other amphibian insulins [14].
  • To clarify whether this molecule belongs to hsc73 itself, the membrane protein fraction of Daudi cells was isolated by Triton X-114 phase separation and the reactivity of this membrane protein fraction was assessed with monoclonal antibodies (mAbs) which react with 70 kDa heat shock protein (hsp) family, i.e., NT22, A15 and 3A3 [15].
  • Similar observations were made when the pair of cysteines (A10-A15) was replaced by either alanine or serine, whereby serine disturbs more than alanine [16].
