Quantitative Proteomics Analysis of the Secretory Pathway
نویسندگان
چکیده
We report more than 1400 proteins of the secretory-pathway proteome and provide spatial information on the relative presence of each protein in the rough and smooth ER Golgi cisternae and Golgi-derived COPI vesicles. The data support a role for COPI vesicles in recycling and cisternal maturation, showing that Golgi-resident proteins are present at a higher concentration than secretory cargo. Of the 1400 proteins, 345 were identified as previously uncharacterized. Of these, 230 had their subcellular location deduced by proteomics. This study provides a comprehensive catalog of the ER and Golgi proteomes with insight into their identity and function.

Analysis of the differential secretome of nasopharyngeal carcinoma cell lines CNE-2R and CNE-2.
Radioresistance is the major cause of poor prognosis in nasopharyngeal carcinoma (NPC). To identify and characterize the secretome associated with NPC radioresistance, we compared the conditioned serum-free medium of radioresistant CNE-2R cells with that of the parental radiosensitive CNE-2 cells using isobaric tags for relative and absolute quantitation (iTRAQ) with liquid chromatography-elect...
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...

Background: HOXA11 and leukemia inhibitory factor (LIF) and basic transcriptional element binding protein1 (BTEB1) are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. In this case-control study, the expression pattern of these mRNA was evaluated in patients with endometriosis at the time of implantatio...

متن کاملProteomic analysis of two functional states of the Golgi complex in mammary epithelial cells.
Organellar compartments involved in secretion are expanded during the transition from late pregnancy (basal secretory state) to lactation (maximal secretory state) to accommodate for the increased secretory function required for copious milk production in mammary epithelial cells. The Golgi complex is a major organelle of the secretory pathway and functions to sort, package, distribute, and pos...
