Target
-
Function
This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis. -
Sequence similarities
Belongs to the peptidase S1 family. Granzyme subfamily.
Contains 1 peptidase S1 domain. -
Cellular localization
Cytoplasmic granule. Cytoplasmic granules of cytolytic T-lymphocytes and natural killer cells. - Information by UniProt

All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution (Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated)
Predicted band size: 27 kDa
Observed band size: 28,65 kDa why is the actual band size different from the predicted?
Exposure time: 8 secondsThe expression of Granzyme B is elevated in stimulated splenocytes. Granzyme B forms complex with its protease inhibitor.
The molecular weight observed is consistent with what has been described in the literature (PMID: 8663264, 17116752, 21919028, 9774654).
Blocking/Diluting buffer and concentration: 5% NFDM/TBST.
