Disease relevance of Gzmm

 

High impact information on Gzmm

 

Biological context of Gzmm

  • We have prepared nested deletions from approximately 3.3 kb of the 5'-flanking region of the RNK-Met-1 gene, and inserted these upstream of the chloramphenicol acetyltransferase (CAT) reporter gene [1].
  • These data are consistent with the NK cell-specific expression of RNK-Met-1 and suggest the potential utility of this gene promoter in the development of transgene models of NK cell biology in vivo [1].
  • The RNK-Met-1 gene comprises 5 exons and spans approximately 5.2 kilobases (kb), exhibiting a similar structural organization to a class of CTL-serine proteases with protease catalytic residues encoded near the borders of exons 2, 3, and 5 [1].
  • The 5'-flanking region of the RNK-Met-1 gene contains a number of putative promoter and enhancer regulatory elements and shares several regions of homology with the 5'-flanking region of the mouse perforin gene [1].
 

Anatomical context of Gzmm

  • These data indicate that RNK-Met-1 is a serine protease with unique activity that is expressed in the granules of large granular lymphocytes [4].
 

Associations of Gzmm with chemical compounds

  • We determined the effects on lysis and the second order inhibition rate constants for five granule protease activities: ly-tryptase, ly-chymase, Met-ase (methionine cleaving), Ser-ase (serine cleaving) and Asp-ase (aspartic acid cleaving) [5].
