rsp-3 encodes an ortholog of human SF2/ASF and member of the SR protein family of nuclear phosphoproteins that are required for constitutive splicing and influence alternative splicing regulation; rsp-3 affects the development of oocytes together with rsr-1, and is required for late embryonic viability; SPK-1 binds directly to and phosphorylates the RS domain of RSP-3 in vitro; the rsp-3 mRNA is predominantly expressed in the germline.
Predicted to enable RNA binding activity. Involved in embryo development. Predicted to be located in nuclear speck. Expressed in PVDL; PVDR; and gonad. Human ortholog(s) of this gene implicated in several diseases, including gastrointestinal system cancer (multiple); lung non-small cell carcinoma (multiple); and urinary system cancer (multiple). Is an ortholog of human SRSF1 (serine and arginine rich splicing factor 1).
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.
