ID:GRAA_HUMAN DESCRIPTION: RecName: Full=Granzyme A; EC=3.4.21.78; AltName: Full=CTL tryptase; AltName: Full=Cytotoxic T-lymphocyte proteinase 1; AltName: Full=Fragmentin-1; AltName: Full=Granzyme-1; AltName: Full=Hanukkah factor; Short=H factor; Short=HF; Flags: Precursor; FUNCTION: This enzyme is necessary for target cell lysis in cell- mediated immune responses. It cleaves after Lys or Arg. Cleaves APEX1 after 'Lys-31' and destroys its oxidative repair activity. Involved in apoptosis. CATALYTIC ACTIVITY: Hydrolysis of proteins, including fibronectin, type IV collagen and nucleolin. Preferential cleavage: -Arg-|- Xaa-, -Lys-|-Xaa- >> -Phe-|-Xaa- in small molecule substrates. SUBUNIT: Homodimer; disulfide-linked. Interacts with APEX1. SUBCELLULAR LOCATION: Isoform alpha: Secreted. Cytoplasmic granule. INDUCTION: Dexamethasone (DEX) induces expression of isoform beta and represses expression of isoform alpha. The alteration in expression is mediated by binding of glucocorticoid receptor to independent promoters adjacent to the alternative first exons of isoform alpha and isoform beta. SIMILARITY: Belongs to the peptidase S1 family. Granzyme subfamily. SIMILARITY: Contains 1 peptidase S1 domain. CAUTION: Exons 1a and 1b of the sequence reported in PubMed:17180578 are of human origin, however exon 2 shows strong similarity to the rat sequence.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
