EXD3: EXD3 (Exonuclease 3'-5' Domain Containing 3) is a gene that plays an important role in cellular processes, although it is less widely studied compared to other genes. The protein encoded by EXD3 is believed to be involved in RNA processing and the regulation of gene expression. While its full range of functions is still being explored, EXD3 is thought to be essential for maintaining RNA stability and integrity, which is vital for proper cell function. Alterations or mutations in EXD3 may affect various biological pathways.
