Summary
Predicted to enable RNA binding activity and sequence-specific double-stranded DNA binding activity. Acts upstream of or within regulation of alternative mRNA splicing, via spliceosome. Predicted to be located in nucleus. Predicted to be active in cytoplasm and nucleoplasm. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and retina. Orthologous to human MBNL2 (muscleblind like splicing regulator 2). [provided by Alliance of Genome Resources, Apr 2022]
Expression
Ubiquitous expression in bladder adult (RPKM 30.1), cerebellum adult (RPKM 20.2) and 28 other tissues See more

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.
