snr-1 encodes an ortholog of human small nuclear ribonucleoprotein Sm D3, a protein that forms part of a heptameric complex required for the biogenesis and function of the snRNPs that catalyze mRNA splicing; in combination with the gene that encodes the human Sm B ortholog (snr-2) snr-1 affects embryonic viability and the nuclear association and localization of P granules in embryos based on an RNAi assay, snr-1 also affects embryonic viability, growth, and fertility based on large-scale RNAi assays; snr-1 is expressed in embryos and is expressed in larvae and adults in muscles of the alimentary system, in body-wall muscle, in seam cells and other unidentified cells.
Predicted to enable RNA binding activity. Predicted to be involved in spliceosomal snRNP assembly. Located in P granule. Expressed in germ line; gonad; head; and tail. Human ortholog(s) of this gene implicated in systemic lupus erythematosus. Is an ortholog of human SNRPD3 (small nuclear ribonucleoprotein D3 polypeptide).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
