Pin1At encoding a peptidyl-prolyl cis/trans isomerase regulates flowering time in Arabidopsis.

abstract：:One of the earliest steps in metazoan pre-mRNA splicing involves binding of U2 snRNP auxiliary factor (U2AF) 65 KDa subunit to the polypyrimidine (Py) tract and of the 35 KDa subunit to the invariant AG dinucleotide at the intron 3' end. Here we use in vitro and in vivo depletion, as well as reconstitution assays usin...
