IMP1 (Insulin-like Growth Factor 2 mRNA Binding Protein 1) is a member of the IGF2 mRNA binding protein family, mainly affecting cell proliferation and differentiation by regulating mRNA stability and translation. Composed of several RNA binding domains, IMP1 can specifically bind to target mRNAs. It is expressed in a variety of cell types, especially significant during embryonic development and stem cell self-renewal. The expression of IMP1 is tissue-specific, and changes in its expression level are closely associated with the development of various cancers. Specific gene mutations or dysregulation may lead to abnormal cell growth, increasing the risk of certain genetic diseases and cancers.
