gtl-1 encodes a TRPM subfamily member of the TRP channel family that affects the periodicity of the defecation cycle in combination with gon-2; expression includes the intestine.
Predicted to enable monoatomic cation channel activity. Involved in defecation. Predicted to be located in membrane. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis-parkinsonism/dementia complex 1; cataract; and congenital stationary night blindness 1C. Is an ortholog of human TRPM1 (transient receptor potential cation channel subfamily M member 1); TRPM3 (transient receptor potential cation channel subfamily M member 3); and TRPM7 (transient receptor potential cation channel subfamily M member 7).
