Antibodies which bind specifically to activin receptor like kinase 3
A new receptor family has been identified, of activin-like kinases. Novel proteins have activin/TGF-β-type I receptor functionality, and have consequential diagnostic/therapeutic utility. They may have a serine/threonine kinase domain, a DFKSRN or DLKSKN sequence in subdomain VIB and/or a GTKRYM sequence in subdomain VIII.
1. An isolated antibody which binds specifically to an amino acid sequence encoded by the nucleotide sequence set forth in SEQ ID NO: 5 (ALK-3).
2. The isolated antibody of claim 1 , wherein the antibody bind specifically to the amino sequence of SEQ ID NO: 6.
3. The isolated antibody of claim 1 , wherein the antibody binds specifically to an extracellular domain of a human protein encoded by the nucleotide sequence set forth in SEQ ID NO: 5.
4. The isolated antibody of claim 1 , wherein the antibody binds specifically to amino acids 181-202 of SEQ ID NO: 6.
