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 branc
hial arch; central nervous system; genitourinary system; limb; and sensory organ. Used to study cerebrocostomandibular syndrome. 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).

Predicted to enable U1 snRNA binding activity and snRNP binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in cytoplasmic ribonucleoprotein granule; fibrillar center; and nuclear speck. Predicted to be part of U1 snRNP; U2-type catalytic step 2 spli
ceosome; and U2-type precatalytic spliceosome. Is expressed in 8-cell stage embryo; central nervous system; olfactory epithelium; submandibular gland primordium; and vibrissa. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPB2 (small nuclear ribonucleoprotein polypeptide B2).
