Crosstalk Summary Mechanically, PCAT6 functions as a scaffold between interferon-stimulated gene 15 (ISG15) and heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1), leading to ISGylation of hnRNPA2B1, thus protecting hnRNPA2B1 from ubiquitination-mediated proteasomal degradation.HNRNPA2B1 is a reader of the N(6)-methyladenosine mark in primary-miRNAs and promotes DROSHA processing to precursor-miRNAs. HNRNPA2B1 downregulated hsa-miR-29a-3p, miR-29b-3p, and miR-222 and upregulated hsa-miR-1266-5p, miR-1268a, miR-671-3p. Transient overexpression of HNRNPA2/B1 reduced breast cancer cellMCF-7 sensitivity to 4-hydroxytamoxifen and fulvestrant, suggesting a role for HNRNPA2/B1 in endocrine-resistance.
