A general role for Rab27a in secretory cells.
Vesicular transport is a complex multistep process regulated by distinct Rab GTPases. Here, we show for the first time that an EGFP-Rab fusion protein is fully functional in a mammalian organism. We constructed a PAC-based transgenic mouse, which expresses EGFP-Rab27a under the control of endogenous Rab27a promoter. The EGFP-Rab27a transgene was fully functional and rescued the two major defect...

متن کاملDevelopment of A Novel Gene Expression System for Secretory Production of Heterologous Proteins via the General Secretory (Sec) Pathway in Corynebacterium glutamicum
Background: Corynebacterium glutamicum (C. glutamicum) is a potential host for the secretory production of the heterologous proteins. However, to this date few secretion-type gene expression systems in C. glutamicum have been developed, which limit applications of C. glutamicum in a secretory production of the heterologous proteins.Objectives: In this stu...
متن کاملDifferential dynamics of Rab3A and Rab27A on secretory granules.
We have assessed the dynamics of the association of Rab3A and Rab27A with secretory granules at various stages of their life in PC12 cells. Endogenous Rab3A colocalised with the secretory granule marker secretogranin II (SGII) and expressed EGFP-Rab3A and ECFP-Rab27A colocalised with one another. The extent of colocalisation between EGFP-Rab3A or EGFP-Rab27 and SGII increased after longer times...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
