Abstract:
We have isolated RPK-2 cDNA from chick embryo cDNA library that encodes a receptor protein kinase of the TGF-beta receptor subfamily. The deduced amino acid sequence reveals the presence of a hydrophobic transmembrane helix and a kinase domain distantly related to type II receptor for TGF-beta. The kinase domain sequence is most similar to RPK-1 identified recently in the chick embryo. Several cysteine residues are contained in the amino-terminal ectodomain, suggesting the protein as a receptor for a peptide growth factor of the TGF-beta family.
