Summary
Enables histone pre-mRNA DCP binding activity. Predicted to be involved in spliceosomal snRNP assembly. Predicted to act upstream of or within protein methylation. Located in cytoplasm and nucleus. Part of histone pre-mRNA 3'end processing complex. Is expressed in several structures, including branchial arch; central nervous system; limb; maxillary process; and sensory organ. Human ortholog(s) of this gene implicated in cerebrocostomandibular syndrome and mixed connective tissue disease. Orthologous to human SNRPB (small nuclear ribonucleoprotein polypeptides B and B1).

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.
