tam-1 encodes a broadly expressed nuclear protein with RING finger, B-box, and glutamine/asparagine-rich domains that promotes signalling in the class B synthetic-multivulva gene pathway (which includes the lin-35/RB gene), and also promotes the activity of genes in multicopy transgenic arrays; the normal role of TAM-1's class B activity is presumably to inhibit RAS pathway activity in vulval development, while TAM-1's effect on transgenes may be through changes in the acetylation state of histones in chromatin; about 3% to 10% of tam-1 transcripts are RNA edited to change A to G resulting in a synonymous change to residue 784 from an L to a L.
Predicted to enable ubiquitin protein ligase activity. Involved in several processes, including chromosome segregation; negative regulation of vulval development; and transcription initiation-coupled chromatin remodeling. Located in germ cell nucleus. Expressed in several structures, including germ line.
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.
