Protein attributes

Sequence length	744 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in TGF-beta pathway. May be a receptor for daf-7. Controls the dauer/nondauer developmental decision in a range of environmental conditions. Regulates body size and male tail patterning. Ref.3
Catalytic activity	ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
Subunit structure	May interact with daf-1 to regulate dauer larva development. Ref.3
Subcellular location	Membrane; Single-pass type I membrane protein.
Tissue specificity	Pharynx, intestine, hypodermis and body wall muscles in L1 through to adult stages. Also expressed in head neurons, ventral cord and tail neurons. Subset of head neurons show coexpression with daf-1 when dauer/nondauer decision is made. Ref.3
Sequence similarities	Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily. Contains 1 protein kinase domain.
