What's a GeneRIF?

once inside the nucleus, P2X6 subunit interacts with the splicing factor 3A1, which ultimately results in a reduction of the mRNA splicing activity
Title: Age-related nuclear translocation of P2X6 subunit modifies splicing activity interacting with splicing factor 3A1.
in macrophages, SF3a has significant preference for mRNA splicing events within innate immune signaling pathways compared with other biological pathways, thereby affecting the splicing of specific genes in the TLR signaling pathway

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
