This does not exclude the possible existence of a cross-talk between SNRPD1 and other ribosome binding proteins such as SF3B1, SF3B2, RPL5, ARCN1, EIF3B, RAN, COPB1, RPL14, VCP, HSPE1, SNRNP200, SARS, EEF2, RPL37, CCT3, KPNB1, RPL23 that have been reported essential for breast cancer survival besides SNRPD1 [14]. This evidence concerns the gene SF3B2 and breast cancer.
