ins-7 encodes an insulin/IGF-1-like peptide; INS-7 is one of 40 insulin-like peptides in C. elegans; INS-7 likely functions as an agonist for the DAF-2 insulin/IGF-1 receptor, as loss of ins-7 activity via RNAi results in: 1) a significantly increased lifespan that is not further extended in long-lived daf-2 mutant animals, and 2) an increased frequency of dauer formation in animals containing an incompletely penetrant daf-2 mutation; an ins-7 promoter fusion is expressed in amphid sensory neurons, labial neurons, the nerve ring, and ventral cord and tail neurons; ins-7 expression is positively regulated by DAF-2-mediated insulin signaling, suggesting that a positive feedback loop involving INS-7 may amplify DAF-2 pathway activity.
Predicted to enable hormone activity. Involved in olfactory learning. Predicted to be located in extracellular region and membrane. Expressed in several structures, including distal tip cell; egg-laying apparatus; head muscle; neurons; and somatic nervous system.
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.
