General annotation (Comments)

Function

Controls the dauer/nondauer developmental decision in a range of environmental conditions. Ref.3

Catalytic activity

ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.

Subunit structure

May interact with daf-4 to regulate dauer larva development. Ref.3

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Head and ventral nerve cord from embryos to adults. Expressed in many sensory neurons. Subset of head neurons show coexpression with daf-4 when dauer/nondauer decision is made. Also expressed in non-neuronal cells: membraneous sheath surrounding the distal end of the intestine and in the distal tip cell of the gonad. Ref.3

Developmental stage

All stages. Ref.3

Sequence similarities

Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.

Contains 1 GS domain.

Contains 1 protein kinase domain.
