PCID2 interacts with proteins involved in multiple stages of RNA processing
(A) IP-western blot of PCID2-Flag in control and stably PCID2-Flag expressing J-Lat 11.1 samples for subsequent mass spectrometry analysis.
(B) Venn diagram of the total individual and common number of identified hits by mass spectrometry in PCID2-Flag over control samples from two independent IP-MS runs.
(C) Network of PCID2 interacting hits identified by mass spectrometry. Hits are classified by cellular function. Gray lines represent PCID2 interacting proteins as analyzed by IP-MS in this study. Red lines represent protein-protein interactions predicted by STRING analysis on experimental evidence only.
