PCID2 Required for B-cell survival through the regulation of the expression of cell-cycle checkpoint MAD2L1 protein during B cell differentiation. As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores. Binds and stabilizes BRCA2 and is thus involved in the control of R-loop-associated DNA damage and transcription-associated genomic instability. R-loop accumulation does not increase in PCID2-depleted cells. Belongs to the CSN12 family. 4 alternatively spliced human isoforms have been reported.
