Table 1. Tandem affinity purification using FIGL1 and FLIP as baits.

Two replicates of Tandem affinity purifications (TAP1 and TAP2) followed by mass spectrometry were performed using either FIGL1 (A) or FLIP (B) as a bait over-expressed in cultured cells. For filtering specific and false positive interactors, refer to Materials and Methods and [36]. The number of peptides and the fraction of the protein covered are indicated for each hit. Raw data are presented in S1 Table.

A	Bait = FIGL1	TAP 1		TAP 2
	protein name	Number of peptides	protein coverage %	Number of peptides	protein coverage %
	FIGL1	47	70,5	42	62,3
	FLIP	34	39,4	30	36,8
B	Bait = FLIP	TAP 1		TAP 2
	protein name	Number of peptides	protein coverage %	Number of peptides	protein coverage %
	FLIP	33	40,6	37	46,2
	FIGL1	18	33,2	22	40,5
