Mutation of the presumptive catalytic serine in Osw3 blocks the processing of Osw3 pro-domain and results in increased spore wall permeability, suggesting that proteolytic activity of Osw3 is necessary for proper assembly of the outer layers of the spore wall.
Apart from this alpha-1 antitrypsin blocks the processing of group antigens (Gag) and envelop proteins (Env), which results in suppression of HIV-1 morphogenesis [ 63].
Three inhibitors, i.e. DAPT, L-685,458 and Compound E, inhibit the protease presenilin forming part of γ-secretase in general, whereas Compound W specifically blocks the processing of one substrate (APP), providing a specificity control.
For example, an A/G SNP that is located at the 24-nucleotide downstream of the 3' end of the mature miR126, can significantly block the processing of pri-miR126 to mature miRNA in the RS4 11 cells (Harnprasopwat et al. 2010).
However, we did observe that Inhibitors of both β and γ-secretases blocked the processing of SMP30, with the former showing maximum effect (Figure 7D).
Even though inhibitors to both β and γ-secretases blocked the processing of SMP30, disparate compartmentalization of SMP30 and secretases preclude us to suggest that secretases are directly responsible for the processing of SMP30.
It is likely that α1-PDX can block the processing of other proteins implicated in the invasive potential of tumor cells, such as growth factors and adhesion molecules, as previously reported in vitro and in vivo models [22], [23], [25], [38].
Finally, recent studies have shown that LIN-28 may recognize the pre-let-7 loop nucleotides and block the processing of human pri-let-7 RNAs into mature miRNAs in embryonic stem cells, suggesting that pre-miRNA loops may be recognized by LIN-28 or LIN-28-like RNA binding factors that control mature miRNA biogenesis [23] [25].
Taken together, these reports support our findings that TRAIL-mediated upregulation of c-FLIPS blocked the processing of caspase-8 at DISC and promoted survival of NSCLC cells.
Thus, the polymerase of an upstream gene may transcribe into the downstream neighbour, interfering with the neighbour's transcription (e.g., by blocking the processing of transcription termination, or by direct collision with another polymerase transcribing the downstream gene).
The INSIG2 gene is a good candidate for being related to obesity because of its function in lipid metabolism, particularly in blocking the processing of SREBPs in response to cholesterol or insulin.
