CLP1 (Cleavage and Polyadenylation Factor 1 Homolog) is a conserved eukaryotic protein initially identified as a component of the mRNA 3′-end processing machinery. It plays a critical role in RNA metabolism, particularly in the cleavage and polyadenylation of precursor mRNAs (pre-mRNAs), tRNA splicing, and surveillance of noncoding RNAs. Structurally, CLP1 contains a kinase domain unique among RNA processing enzymes, enabling ATP-dependent phosphorylation activities essential for its function.
Recombinant CLP1 protein is engineered for in vitro studies to dissect its molecular mechanisms. Produced via bacterial or mammalian expression systems, it retains enzymatic activity for biochemical assays, including RNA binding, kinase activity profiling, and interaction studies with partner proteins like tRNA splicing endonuclease (TSEN) complex. Research on CLP1 gained momentum after discoveries linking its mutations to human disorders. For instance, homozygous CLP1 mutations were associated with progressive neurological defects, including motor-sensory neuropathy and intellectual disability (Science, 2013). Additionally, defective CLP1 in mice causes tRNA splicing failure, leading to neurodevelopmental abnormalities (Nature, 2014).
CLP1 recombinant protein is instrumental in exploring RNA quality control pathways and therapeutic targets. Recent studies highlight its dual role in mRNA and tRNA processing, with implications in cancer biology and neurodegeneration. For example, CLP1 overexpression has been observed in certain tumors, suggesting potential oncogenic roles, while its dysfunction correlates with tRNA fragment accumulation in neurodegenerative models. These findings position CLP1 as a nexus between RNA metabolism and disease, driving interest in its structure-function relationships and therapeutic modulation. Current applications include drug screening platforms and disease modeling using patient-derived mutations to unravel pathogenic mechanisms.
