SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus
text	spliceosome

basic FUNCTION	accelerating the folding of proteins by catalyzing the cis-trans isomerization of proline imidic peptide bonds in oligopeptides
	may be involved in muscle- and brain-specific processes
	may be involved in pre-mRNA splicing
	negatively regulates the function of MLL

CELLULAR PROCESS	nucleotide, transcription, regulation
	nucleotide, RNA splicing
	protein, post translation, folding

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

identified in the spliceosome C complex

INTERACTION

DNA

RNA	binding to poly(A)(+)RNA

small molecule	cofactor, nucleotide,
	NADPH

protein	flavoprotein P450 oxidoreductase (POR)
	binding to cyclosporin A
	mediates downregulation of the expression of MLL target genes HOXC8, HOXA9, CDKN1B, and C-MYC, in a proline isomerase-dependent manner

cell & other

REGULATION

Other
