The RNA, U3 small nucleolar interacting protein 2 (RNU3IP2), also known as RRP9 or U3-55K, is a conserved nucleolar protein involved in ribosome biogenesis. It interacts with the U3 small nucleolar RNA (snoRNA), a key component of the small subunit (SSU) processome, which facilitates 18S rRNA processing during ribosome assembly. RNU3IP2 plays a critical role in the early stages of rRNA maturation, particularly in the cleavage and modification of ribosomal RNA precursors within the nucleolus. Structurally, it contains an N-terminal acidic domain and a C-terminal RNA-binding region, enabling interactions with snoRNAs and other processing factors. Though its molecular mechanisms are not fully elucidated, studies suggest its involvement in cell proliferation, mitochondrial function, and metabolic regulation. Dysregulation of RNU3IP2 has been loosely associated with cancers, metabolic syndromes, and neurodegenerative disorders, though evidence remains preliminary. Current research focuses on clarifying its precise roles in cellular homeostasis and disease pathways. Limited functional studies and absence of detailed structural data highlight the need for further investigation into this undercharacterized protein.
