that the WA mutation attenuated the transport of Alca protein for the plasma membrane. We next quantified the amount of liberated ectodomain generated from the AP-fusion proteins of wild-type or WA mutant Alca. Offered that the transport of the WA mutant proteins to the cell surface was attenuated, if the [http://robustgames.com/members/sand2jump/activity/653964/ These findings indicate a causal part for ASM in RGDfV-induced apoptosis in ECV-304] majority of the Alca protein was cleaved upon or soon after reaching the cell surface, the extracellular secretion of the cleaved ectodomain proteins ought to also be attenuated. However, no important difference was observed inside the level of extracellularly liberated AP activity in between the wild type- and WA mutant-expressing cells. Collectively, these observations recommended that the Alca protein is a minimum of partly cleaved en route for the cell surface. To examine if the cleavable WA mutant protein was effectively processed, we next expressed the untransported mutant Alca in CAD cells. The C-terminal fragment from the primary cleavage item from the WA mutant was only faintly detected, suggesting that the WA mutant could possibly not be cleaved. Nevertheless, the Alca CTF is additional cleaved by c-secretase to generate p3-Alca and Alca ICD, as well as the latter is promptly degraded by an unspecified mechanism, so tiny Alca ICD is detected in mouse brain, but Alca CTF is readily detected. To Alcadein Cleavage for Kinesin-1 Distribution determine if Alca CTF was truly developed in the WA mutant, the c-secretase inhibitor DAPT was added for the culture. In the presence of DAPT, a comparable amount of Alca CTF was made in the WA mutant and wild-type Alca, indicating that the main cleavage occurred inside the WA mutant Alca. To additional examine if a further c-secretase cleavage solution, p3Alca peptide, was correctly generated in the WA mutant, p3Alca peptide liberated in to the culture medium was collected with anti-p3-Alc antibodies, and detected by mass spectrometry as described previously. The p3-Alca peptide was readily detected within the culture medium on the WA mutant-expressing cells as in that of wild-type Alca expressing cells. The molecular weights of the p3-Alca peptides and their proportions derived from the WA mutant were identical to these derived from wild-type Alca. These findings collectively indicated that the WA mutant Alca was properly processed to generate bona fide p3-Alca peptide, and therefore that this processing was largely unaffected by the inappropriate retention of Alca within the cells. Attenuation of Alca cleavage results in aberrant peripheral localizations of KLC1 and kinesin heavy chain We next addressed why Alca, which can be produced as a transmembrane protein, needs to become cleaved with such outstanding efficiency en route towards the cell surface that tiny full-length Alca protein resides there. As described previously, Alca binds to KLC to activate kinesin-1's association with Alcacontaining vesicles, and Alca's WD motif is adequate to recruit kinesin-1 to these vesicles to activate their anterograde transport. These findings led us to speculate that, if Alca stayed on the cell surface, it could inappropriately recruit kinesin-1 towards the cell periphery. To assess the possibility, we expressed an uncleavable Alca mutant protein together with KLC1 in CAD cells. The FLAGtagged KLC1 protein expressed alone was evenly distributed within the cytoplasm.
