The unique proline-rich domain of parotid proline-rich proteins functions in secretory sorting.
When expressed in pituitary AtT-20 cells, parotid proline-rich proteins enter the regulated pathway. Because the short N-terminal domain of a basic proline-rich protein is necessary for efficient export from the ER, it has not been possible to evaluate the role of this polypeptide segment as a sorting signal for regulated secretion. We now show that addition of the six-amino acid propeptide of ...
متن کاملSalt Stress Encourages Proline Accumulation by Regulating Proline Biosynthesis and Degradation in Jerusalem Artichoke Plantlets
Proline accumulation is an important mechanism for osmotic regulation under salt stress. In this study, we evaluated proline accumulation profiles in roots, stems and leaves of Jerusalem artichoke (Helianthus tuberosus L.) plantlets under NaCl stress. We also examined HtP5CS, HtOAT and HtPDH enzyme activities and gene expression patterns of putative HtP5CS1, HtP5CS2, HtOAT, HtPDH1, and HtPDH2 g...
متن کاملThe importance of being proline: the interaction of proline-rich motifs in signaling proteins with their cognate domains.
Acommon focus among molecular and cellular biologists is the identification of proteins that interact with each other. Yeast two-hybrid, cDNA expression library screening, and coimmunoprecipitation experiments are powerful methods for identifying novel proteins that bind to one's favorite protein for the purpose of learning more regarding its cellular function. These same techniques, coupled wi...
متن کاملThe structure and function of proline-rich regions in proteins.
Proline is a very unusual amino acid, in that the side-chain is cyclized back on to the backbone amide position. This has three important consequences. First, the backbone conformation of proline itself is very restricted. The available backbone sb dihedral angles are limited to a small range around = -65 [1,2] (Figure 1). Similar restrictions do not apply to i/, which is able to populate eithe...
متن کاملProline accumulation and osmotic stress: an overview of P5CS gene in plants
Under osmotic stresses, proline accumulation is an important response of plants to these conditions. Proline is a compatible osmolyte which affects many cellular and molecular aspects of plant in both normal and stressful situations. Proline is shown to be involved in plant development in normal condition and in conferring resistance to plant under biotic and abiotic stresses. Therefore, many s...
