Table 3. Different features employed to study their contribution towards observed correlation between RBPs and their post-transcriptional targets, in the transcript centric modelling.

Variable	Feature name	Description
Response	Correlation coefficient of RBP with target transcript	For each RBP, the correlation coefficient of the selected protein coding transcript (or protein expression at protein level) with each target transcript was selected as the response variable.
Predictor	CLIP Signal	CLIP peaks in the bed format obtained from CLIPdb28 come with a P- value signifying the intensity of the CLIP binding for each binding site. The median P - value of the binding sites which were mapped on to the target, for each RBP, was calculated.
	Distance of binding site from 5′ end	The distance of the start of the binding site from the 5′ end of each target transcript was calculated.
	Distance of binding site from 3′ end	The distance of the start of the binding site from the 3′ end of each target transcript was calculated.
	Transcript Length	The length of each target transcript was obtained from Ensembl51.
	Transcript Type	The biotype of each target transcript was also obtained from Ensembl51.

For each feature details about how it was computed is also listed.
