KHDRBS2 (KH RNA-binding domain-containing, signal transduction-associated protein 2), also known as Sam68-like protein or SLM2. is a member of the STAR (signal transduction and activation of RNA) family. It is characterized by a conserved KH (heterogeneous nuclear ribonucleoprotein K homology) domain that enables RNA binding and a divergent C-terminal region rich in regulatory motifs. This protein plays a role in post-transcriptional gene regulation, including mRNA splicing, stability, and translation, by interacting with specific RNA sequences and cellular signaling pathways.
Expressed in various tissues, KHDRBS2 is implicated in cellular processes such as cell cycle control, differentiation, and apoptosis. Studies link it to cancer progression, where aberrant expression may influence tumor proliferation and metastasis through interactions with oncogenic RNAs or signaling cascades like MAPK/ERK. In neurological contexts, KHDRBS2 is associated with synaptic plasticity and neurodevelopment, with potential roles in neurodegenerative and neurodevelopmental disorders.
Recombinant human KHDRBS2 protein is engineered for in vitro studies using expression systems like *E. coli* or mammalian cells. Its purified form enables functional analyses, including RNA-binding assays, protein interaction studies, and drug discovery targeting RNA-mediated diseases. Structural features like tyrosine phosphorylation sites and RG-rich motifs further highlight its regulatory versatility in signal-responsive RNA metabolism. Research continues to explore its therapeutic potential and mechanistic details in health and disease.
