Summary
Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in nuclear speck. Predicted to be part of U2 snRNP and spliceosomal complex. Is expressed in early conceptus; inner cell mass; and oocyte. Orthologous to human SF3B2 (splicing factor 3b subunit 2). [provided by Alliance of Genome Resources, Apr 2022]

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.
