	Other Details	:	GENE EXPRESSION WAS INDUCED BY THE ADDITION OF IPTG TO A FINAL CONCENTRATION OF 0.5 MM AND THE CELLS WERE INCUBATED FOR 3 H AT 37 DEGREES C. THE CELLS WERE HARVESTED BY CENTRIFUGATION AT 6000 RPM FOR 20 MIN AND STORED AT -20 DEGREES C UNTIL REQUIRED. THE CELLS WERE RESUSPENDED IN TE BUFFER (CONTAINING 1 MM EDTA, 25 MM TRIS) AT PH 8.0 AND THEN BROKEN IN A FRENCH PRESS. THE CELL DEBRIS WAS REMOVED BY CENTRIFUGATION AT 40000 G FOR 30 MIN, FOLLOWING WHICH THE PELLET WAS RESUSPENDED IN 50 ML OF 20 MM SODIUM PHOSPHATE CONTAINING 10 PER CENT TRITON X-100 AND 100 MM SODIUM CHLORIDE. THE CRUDE EXTRACT WAS ADDED TO 6 ML OF NI-NTA RESIN (QIAGEN), MIXED FOR 2 H AT 4 DEGREES C, SPUN DOWN AT 5000 G FOR 10 MIN AND THE SUPERNATANT DISCARDED. THE BEADS WERE LOADED ON TO A COLUMN, WASHED WITH 2 VOLUMES OF RESUSPENSION BUFFER AND THEN 2 VOLUMES OF ELUTION BUFFER (CONTAINING 500 MM IMIDAZOLE, 50 MM SODIUM CHLORIDE AND 20 MM SODIUM PHOSPHATE). THE ELUATE WAS DESALTED ON A SEPHADEX G-25 PD-10 COLUMN (PHARMACIA) AND THEN CONCENTRATED TO 1 MM USING A BIOMAX 10K MEMBRANE TO A FINAL VOLUME OF 500 MICROLITRES. THE PROTEIN PRODUCT CORRESPONDS TO RESIDUES 81 TO 214 OF FULL LENGTH PXQUA, WITH A C-TERMINAL HIS6 EXTENSION

Chain A (QKIB_XENLA | Q6IRN2)

molecular function
	GO:0003723	RNA binding	Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
	GO:0003676	nucleic acid binding	Interacting selectively and non-covalently with any nucleic acid.
biological process
	GO:0008380	RNA splicing	The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.
	GO:0030154	cell differentiation	The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
	GO:0006397	mRNA processing	Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
	GO:0051028	mRNA transport	The directed movement of mRNA, messenger ribonucleic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0007275	multicellular organism development	The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
	GO:0006417	regulation of translation	Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
	GO:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005634	nucleus	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
