Table 3. mRNA pull-down using GFP-tagged proteins after 30 min under osmotic stress (0.6 M KCl).

The mRNA enrichment to one another was calculated as the ratio (PD/I)mRNA1/(PD/I)mRNA2, where PD is the relative amount of the specified mRNA detected in the pull-down using an specific GFP-tagged protein and I (input) is the relative amount of that mRNA in the cell extract prior to the pull-down. The levels of specific mRNAs were quantified by qPCR and the unspecific RNA pulled down from an untagged strain (BY4741) was used to normalize. His2p and Clb2p were included as controls of proteins that do not bind those mRNAs.

	Ratio (PD/I)mRNA1/(PD/I)mRNA2
GFP tagged protein	GPD1/ASH1	GPD1/HYP2	STL1/ASH1	STL1/HYP2
Pat1p	5.88*	3.30*	7.07*	3.97*
Lsm1p	5.40*	0.60*	7.86*	0.90*
Lsm3p	4.61	1.46	6.30	2.00
Lsm4p	4.87*	0.44*	5.12*	0.46*
Lsm7p	2.79	1.25	3.44	1.54

NM, non-measurable (mRNA2 was not detected in pull-down)
