| abstractText | Previous studies have indicated that proopiomelanocortin (POMC) is translationally regulated. We proposed that the regulatory mechanism involves an interaction between trans-acting protein factors and a cis-acting stem-loop structure in the coding region of POMC mRNA. Functional interactions were tested by examining the translation of mouse POMC mRNA in a rabbit reticulocyte system. Specific binding was demonstrated with ultraviolet-crosslinking and RNA gel mobility shift assays. The evidence presented supports our hypothesis that the translational regulation of POMC gene expression involves recognition of the stem-loop by RNA-binding proteins. Furthermore, POMC stem-loop RNA-binding proteins specifically recognized a predicted stem-loop found in the coding region of corticotropin-releasing hormone, suggesting a novel mechanism of gene regulation that may extend to other neuropeptides as well. |
