TXNL4B Protein, vital for pre-mRNA splicing, is crucial for S/G (2) cell cycle transition, forming homodimers and interacting with the U5-102 kDa spliceosome subunit. It plays a key role in splicing intricacies and influences cell cycle dynamics. TXNL4B Protein, Human (His) is the recombinant human-derived TXNL4B protein, expressed by E. coli , with N-His labeled tag.
