IPR024942 is a Maturase MatK, N-terminal domain.
<p>Group II introns are widespread in plant cell organelles [[cite:PUB00043292]]. In vivo, most plant group II introns do not self-splice, but require the assistance of proteinaceous splicing factors, known as maturases. In higher plants, maturases are encoded for in the nuclear genes [[cite:PUB00043293]], but are otherwise encoded by organellar introns.</p> <p>Maturase MatK is usually encoded in the trnK tRNA gene intron, and probably assists in splicing its own and other chloroplast group II introns.</p> <p>The N-terminal domain of MatK appears to be a divergent reverse transcriptase domain that has lost most of the conserved sequence motifs typical of functional reverse transcriptases [[cite:PUB00004435]]. The function of this domain is not known, but it may be important in RNA splicing.</p>
