Title	Profiling of protein interactions of the circRNA cZNF292 in endothelial cells
Description	Circular RNAs are a class of non-coding RNAs mostly generated by back-splicing RNA transcripts of protein-coding gene loci. In difference to canoncial splicing, back-splicing ligates downstream splice donor site with an upstream splice acceptor generating a covalently closed circular RNA. CircRNAs have been reported to influence cellular functions by acting as miRNA sponges, regulation of host gene transcription or by protein interactions. The circRNA cZNF292 has been previously reported to be regulated under hypoxia and to influence endothelial cell angiogenesis and functions. The present data set aims to identfy protein interactions partners of cZNF292 in endothelial cells to further characterize the mechanism of action of cZNF292. Dataset comprises 8 replicates of proteins identified after biotin-based 2'O-Me RNA antisense affinity purification of the circRNA cZNF292 from HUVEC (human umbilical vein endothelial cell) lysates compared to a control probe dataset. Purification was performed without cross-linking under low salt and mild detergent conditions.
