Several studies demonstrate that STRAP acts as a scaffold and regulatory adaptor in key tumor suppressive and oncogenic pathways. For example, STRAP interacts with the central DNA‐binding region of p53, displacing its negative regulator Mdm2 to potentiate p53-mediated transcription, apoptosis, and cell cycle arrest, while also modulating the stability of oncogenic drivers such as c-Jun and β-catenin. These activities highlight STRAP’s dual ability to promote cell death under certain conditions and enhance tumor cell invasion and metastasis in others."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "4"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its roles in modulating cell survival and proliferative signaling, STRAP is emerging as a critical regulator of RNA metabolism and translational control. It facilitates the assembly of the spliceosomal snRNP machinery—for instance, by interacting with core components of the SMN complex and Gemin proteins—to govern alternative splicing events that are essential for lineage commitment during embryogenesis. Moreover, STRAP is tethered to specific mRNAs (such as those encoding collagen polypeptides) via RNA-binding proteins, thereby restraining excessive translation and ensuring the coordinated synthesis necessary for proper protein assembly.
