sid-3 encodes a nonreceptor tyrosine kinase that is a member of the activated cdc-42-associated kinase (Ack) subfamily of cytoplasmic tyrosine kinases; in C. elegans sid-3 functions to regulate the import of dsRNA into cells, thus affecting the efficiency of RNA-mediated gene silencing (RNAi); SID-3 localizes to the cytoplasm.
Predicted to enable non-membrane spanning protein tyrosine kinase activity and signaling receptor binding activity. Involved in regulatory ncRNA-mediated post-transcriptional gene silencing. Located in cytoplasm. Expressed in several structures, including excretory canal; intestine; phasmid neurons; rectal gland cell; and somatic cell. Is an ortholog of human TNK2 (tyrosine kinase non receptor 2).
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.
