The heavy chain is important for docking and endocytosis of BoNT-A in the nerve end terminal, while the light chain cleaves SNAP-25 protein in the nerve end terminal, SNAP-25 being essential in the fusion of acetylcholine vesicles with the nerve end terminal membrane [17].
For Kip2, the genomic kip2 locus was modified using homologous recombination to add an inducible Gal1 promoter, an N-terminal His8-ZZ tag and Tev cleavage site, and a C-terminal SNAP tag.
We used superresolution microscopy (Betzig et al., 2006; Hess et al., 2006; Rust et al., 2006) to resolve the distribution of individual Sla1 proteins at the endocytic site: We fixed cells expressing Sla1 fused to a C-terminal SNAP tag and imaged structures on the bottom membrane of the cell close to the coverslip surface.
Here, we show that SNAP-251 180 SNAP-251 180-terminan SN-terminalain, but not SNAP-251–206 (S206), inhibits Kv current andomainnces glucose-dependent insulin secretion from rat pancreatic islet β-cells, and furthermore, this enhancement was induced butthe blockade of the Kv2.1 currenot
We inserted cleavable tags for affinity purification and a C-terminal SNAP-tag (giving the option of covalent labeling).
To generate N-terminal SNAP-tagged A3 and A3 W243F, the methionine start signal was removed from cDNA encoding the full length A3 and subcloned into a vector (pSEMS) containing a 5HT3-receptor-derived signal sequence followed by the SNAP tag (New England Biolabs, Ipswich, MA, USA).
The N-terminal tagging of SNAP-CD59, SNAP-FOLR1 and SNAP-PrP was obtained by inserting the SNAPtag domain following the N-terminal signal peptide of each protein.
All the lung samples were harvested at a terminal anesthesia point, snap frozen in liquid nitrogen, and stored at −80°C for RNA or hydroxyproline content analysis.
The procedure of sucrose perfusion and dissection of the spinal cord was conducted rapidly, within a maximum of ten minutes from terminal anaesthesia to snap freezing of tissue, to ensure optimal preservation of RNA quality.
The Q group can be further divided into three subgroups according to their overall homology in the SNARE domain: Qa (or syntaxins), Qb (or SNAP N-terminal) and Qc (or SNAP C-terminal) [44].
The Q group can be further divided into three sub-groups according to their overall homology in the SNARE domain: Qa (or syntaxins), Qb (or SNAP N-terminal) and Qc (or SNAP C-terminal) [ 11].
